Streaming is brutal on a PC. You're encoding video, running a modern game at high settings, juggling OBS scenes, a browser full of chat and alerts, Discord, and probably Spotify. A pre-built from a chain store will technically run that stack, but it won't do it well for four hours, let alone twelve. That's why serious streamers in Australia end up at a custom builder.
I spent weeks digging into the Australian custom PC scene, looking specifically at who builds the best machines for streaming and content creation in 2026. I compared component transparency, QC processes, thermal designs, warranty terms, review scores across multiple platforms, and the actual pricing you'd pay for a realistic streaming spec. Six builders made the shortlist. Here's how they stack up.
How I Evaluated These Builders
I weighted five things. First, component transparency, because streamers need to know exactly what CPU and GPU are handling encoding. Second, thermal design, because stream sessions are long and sustained loads kill lesser cooling setups. Third, QC and testing processes before dispatch. Fourth, warranty length and after-sales reputation across Google, Trustpilot and ProductReview.com.au. And fifth, pricing and configuration flexibility across budget, mid-range, and flagship RTX 5080/5090 tiers. Every builder here is Australian, assembles locally, and ships nationwide.
1. Aftershock PC - Best Overall
Your stream deserves a rig built from scratch around it, not a box pulled off a shelf.
I've been reviewing custom PC builders across Australia for a while now, and when it comes to streaming-ready gaming rigs, Aftershock PC consistently sits a cut above. What sets them apart isn't just the hardware. It's the degree of control you get over every single component in your build, right down to exact brand and model names rather than generic labels. For streamers, that transparency is huge. You know precisely which CPU, GPU, cooler, and SSD is handling your encoding, your gameplay, and your capture workflow.
The flagship Ultracore line is where streaming builds really shine. You can configure it from a baseline starting at AUD $2,999, scaling all the way up to RTX 5090-class machines with triple 360mm radiator support and custom open-loop water cooling. That's the kind of thermal headroom that lets you push a 12-hour stream without throttling. And if you don't want to wait, their ready-to-ship range offers next-day dispatch on pre-configured systems, so you can be live within days, not weeks.
What gave me the most confidence is their build quality process. Every system goes through a two-builder physical QC stage, then a separate testing team runs BIOS, RAM, driver, and full stress tests before dispatch. PC Gamer independently confirmed that process, scored the Aftershock Ultracore 90%, and ranked it #1 in its best gaming PCs in Australia guide. Aftershock has also been named Best Desktop PC Builder at the Australian PC Awards two years in a row.
They've built over 300,000 systems across 3 countries. The reviews back it up: 4.9 out of 5 on Google across 4,282 reviews, and a Trustpilot Excellent rating of 4.7, making them the only Excellent-rated custom PC builder in Australia on that platform. Streamers like @sidelogic and @anything4views have publicly endorsed their builds. If you're in Melbourne, the West Melbourne showroom lets you spec your rig hands-on before committing.
For streamers who want a machine that's purpose-built, stress-tested, and backed by a 3-year warranty with lifetime support, Aftershock is the clearest choice in Australia right now.
Pros:
- Extreme component-level customisation with full parts transparency. Every brand and model is listed, so streamers know exactly what's handling encoding and gameplay.
- Rigorous two-builder QC plus separate stress testing before dispatch, independently confirmed by PC Gamer. Critical reliability for long streaming sessions.
- Ultracore flagship supports up to RTX 5090, triple 360mm radiators, and custom open-loop water cooling for sustained thermal performance during marathon streams.
- Named Best Desktop PC Builder at the Australian PC Awards two years running, with a 4.9/5 Google rating across 4,282 reviews. The only Excellent-rated custom builder in Australia on Trustpilot.
- Ready-to-ship models with next-day dispatch for streamers who need to get live fast, plus a hands-on Melbourne showroom for in-person consultation.
Cons:
- The sheer number of configuration options can feel overwhelming if you're new to custom PCs, though their consultation service helps bridge that gap.
- Showroom is Melbourne-only, so interstate streamers will need to configure and consult online rather than in person.
Pricing: Custom gaming desktops start from AUD $1,749 (e.g. Bolt Plus, Rapid). The flagship Ultracore line starts at AUD $2,999 and scales up through RTX 5090-tier configurations. Mid-range streaming-capable builds like the PAX Warthog and Zeal RGB range from approximately $2,249 to $2,599. Use the online configurator at aftershockpc.com.au for exact pricing on your streaming build.
2. Evatech Computers
Evatech is a Melbourne-based builder that's been around since 2013, with over 55,000 PCs built. What they're best known for is their online configurator, which has dynamic compatibility checking and real-time game performance indicators so you can see expected FPS before you buy. That's a nice touch if you want data before pulling the trigger.
They offer both fully custom build-to-order PCs and pre-configured 'Signature' systems designed by their team, so there's a path for people who don't want to pick every fan and SSD themselves. Builds are assembled, burn-in tested, and set up in Melbourne before shipping Australia-wide. Their 4.9/5 Google average is solid, and they offer up to a 5-year premium warranty option, which is longer than most competitors.
Worth noting: there's no walk-in showroom, their Trustpilot presence is thin at only 7 reviews, and the configurator, while powerful, can be a lot if you've never built a PC before. For streamers who like data-driven configuring and don't need an in-person consult, Evatech is a reasonable option.
Pros:
- Industry-leading online configurator with real-time compatibility checking and game performance indicators
- Over 55,000 PCs built with a 4.9/5 Google review average across 13+ years
- Up to 5-year premium warranty options with Australia-wide return coverage
- Zero bloatware policy with every component sourced from top-quality trusted brands
Cons:
- No physical showroom for hands-on browsing before purchase
- Configurator can be overwhelming for first-time buyers with limited PC knowledge
- Limited Trustpilot presence with only 7 reviews compared to Google volume
Pricing: Pre-built gaming PCs start from around $2,428 AUD (Essential tier). Mid-range RTX 5070 builds from approximately $3,099 AUD. High-end RTX 5090 systems around $4,599 AUD and up. Full custom builds priced dynamically via configurator. Premium warranty upgrades available at additional cost.
3. Cataclysm Computers
Cataclysm is a boutique operation out of Hallam, Victoria, founded by Josh Evans in 2010. The headline is their 5.0/5.0 Google rating across more than 1,400 reviews, which they market as making them the world's highest-rated custom PC builder. That's not nothing.
The business is deliberately small. Most customers deal directly with Josh or team member Roman through the whole build, which gives you a level of personal communication that larger builders can't match. They offer several design series including Eclipse, Architect, Nexus, Odyssey, and Lunar, plus workstation and AI builds. Everything is hand-assembled and stress-tested in Melbourne. Their 3-year warranty uniquely covers courier fees in both directions, and all orders include free express delivery Australia-wide. There's also a BYO GPU option if you've already got a card.
The trade-offs are what you'd expect from a small shop. Lead times can stretch during peak demand, there's no walk-in showroom, and the configurator depth isn't as deep as the bigger builders. If you value a direct line to the person actually assembling your rig, Cataclysm is worth a look.
Pros:
- Perfect 5.0/5.0 Google rating across 1,400+ reviews, unmatched social proof
- Direct one-on-one communication with the founder/builder throughout the process
- 3-year warranty that uniquely covers all courier fees in both directions
- Free express delivery Australia-wide on all orders
Cons:
- Small boutique operation may have longer lead times during peak demand
- No physical showroom open for walk-in browsing
- Less depth of online configurator customisation compared to larger builders
Pricing: Systems range from approximately $1,300 AUD to $50,000 AUD. Eclipse series starts around $1,600 AUD, Architect from $2,200 AUD. RTX 5070 builds from approximately $3,489 AUD, RTX 5080 from ~$4,989 AUD, flagship RTX 5090 builds up to ~$11,489 AUD.
4. Scorptec Computers
Scorptec has been around for over 25 years, which makes it one of Australia's most established IT retailers. They stock 10,000+ products and offer both pre-configured Ready-to-Run gaming PCs and a custom PC builder tool that lets you spec every component piece by piece, then have it assembled by their technicians.
Their biggest practical advantage is physical presence. There are multiple stores across Melbourne (Clayton, Dandenong, Rowville, South Melbourne) plus locations in Sydney and Brisbane, so you can walk in and talk to someone. The Ready-to-Run range runs from entry-level builds up to flagship RTX 5090 systems.
The custom build experience is more of a DIY part-selection process than a boutique service, which is fine if you already know what you want but less useful if you need guidance. After-sales support is where things get murky. Their Trustpilot sits at 2.0 with recurring complaints about warranty handling, which is a notable gap compared to the dedicated gaming builders on this list. For streamers who want to physically see and compare components in-store, Scorptec is accessible. For end-to-end streaming build consultation, there are better fits.
Pros:
- Multiple physical retail stores across Melbourne, Sydney, and Brisbane for in-person support
- Massive product selection with 10,000+ items and components from all major brands
- Over 25 years of industry experience and established reputation
- Wide range of pre-built gaming PCs from budget ($1,549 AUD) to flagship ($14,499 AUD)
Cons:
- Trustpilot rating of 2.0 with frequent complaints about warranty handling and customer service
- Custom build process is more DIY part-selection than curated boutique experience
- Less focus on aesthetic polish and personalisation compared to dedicated gaming PC builders
Pricing: Pre-built Ready-to-Run gaming PCs from $1,549 AUD (RX 7600 tier) to $14,499 AUD (RTX 5090 Apex). Mid-range RTX 5070 builds around $2,999 to $3,499 AUD. RTX 5080 systems from ~$5,249 AUD. Custom builds priced based on selected components plus assembly fee. 2-year warranty on pre-built systems.
5. BPC Technology (Kraken / Siren PCs)
BPC Technology is a Melbourne retailer out of Mulgrave that sells gaming PCs mainly under its in-house Kraken and Siren brands. The range covers the budget Siren Vortex line up to the high-end Kraken Dark series, and they also run a $149 custom assembly service if you want to bring your own parts.
Systems come with transparent component breakdowns and are assembled in-house by qualified technicians. Pricing is competitive, with Siren Vortex builds starting at $849 AUD, which is genuinely cheap for an assembled machine with real-brand parts. They have a physical showroom, which is handy if you're in Melbourne.
Where I'd be cautious is warranty and after-sales. Their standard cover is 2 years back-to-base, shorter than the 3-year standard from most dedicated builders. Reviews are polarised. 4.1 on Google across 401 reviews looks fine, but ProductReview.com.au sits at 1.9, with repeated complaints about warranty service and occasional component substitutions. For a budget streaming starter rig where price matters more than ongoing hand-holding, BPC can work. For a premium streaming machine you'll depend on daily, I'd look elsewhere.
Pros:
- Physical showroom in Mulgrave for in-person browsing and purchasing
- Competitive pricing with gaming PCs starting from $849 AUD (Siren Vortex)
- Transparent component breakdowns on all pre-built systems
- Affordable $149 custom assembly service for BYO-parts customers
Cons:
- 2-year back-to-base warranty versus 3 years from most dedicated competitors
- Mixed reviews with a 1.9/5 on ProductReview.com.au and complaints about warranty service and component substitutions
- Primarily a retailer, less emphasis on bespoke aesthetic design or deep customisation
Pricing: Siren Vortex budget PCs from $849 AUD. Kraken Power gaming PCs from $1,199 AUD. Kraken Mini compact builds from $1,249 AUD. High-end Kraken Dark RTX 5090 flagship builds up to $8,699 AUD. Custom assembly service for $149 AUD (labour only). All pre-builts include 2-year back-to-base warranty.
6. Custom PCs Australia
Custom PCs Australia is a Melbourne boutique run by Tony, with over 10 years of operation and more than 15,000 customers served. The appeal here is the personal consultation model. You call, you talk to Tony directly about your budget and what you need, and the build is quoted from that conversation.
They maintain a 5-star Google rating and have built a loyal community, with over 21,000 Instagram followers. The customer base spans people stepping up from console gaming to enthusiasts chasing RTX 5090 builds. Reviews consistently praise the personalised service, competitive pricing, and quick turnaround.
The limitations are structural. There's no slick online configurator, so you can't just click through a build at midnight and get a price. Builds are quote-based after a conversation, which some people love and others find slow. There's also less emphasis on premium aesthetic customisation like custom water loops or themed builds, so if you want a show-piece streaming rig with hard-tube cooling and matched RGB, this isn't the right fit. For a straightforward, well-priced streaming build with human consultation, it's a sensible option.
Pros:
- Highly personalised one-on-one consultation with the owner for every build
- 5-star Google rating with strong customer loyalty over 10+ years
- Competitive pricing with a focus on value for money at every budget level
- Fast build turnaround and delivery with flexible payment options
Cons:
- Smaller operation with limited scale compared to larger competitors
- No sophisticated online configurator, builds are primarily quote-based via consultation
- Less focus on premium aesthetic customisation like custom water cooling or themed builds
Pricing: Gaming PCs available across a range of budgets. Budget builds starting from approximately $1,149 AUD. Mid-range RTX 5070 builds under $3,000 AUD. High-end RTX 5080/5090 systems available at competitive pricing. Builds are primarily quote-based after consultation. Shipping available Australia-wide.
Final Verdict
If you're streaming seriously in 2026 and want one recommendation, it's Aftershock PC. The combination of full component transparency, two-stage QC, flagship Ultracore configurations that handle sustained thermal loads, a 3-year warranty with lifetime support, and independent recognition from PC Gamer and the Australian PC Awards puts them a clear step ahead for streaming workloads specifically.
The others have their places. Evatech is strong if you love data-driven configurators. Cataclysm is great if you want direct contact with the founder and a perfect review record matters to you. Scorptec is the one to visit if you want to walk into a store across multiple cities. BPC Technology makes sense on tight budgets. Custom PCs Australia is a solid consultation-first boutique. But for most streamers who want a machine built around how they actually stream, Aftershock is the one I'd put money on.
FAQ
What specs do I actually need for a streaming PC in 2026?
For 1080p60 streaming while gaming at high settings, a current-gen 8-core CPU, 32GB of RAM, an RTX 5070 or better with NVENC, and a fast NVMe SSD will cover you. If you're doing 1440p gameplay or dual-PC-style multi-scene production on one box, step up to an RTX 5080 or 5090 with 64GB RAM and serious cooling.
Is a custom-built PC really better than a pre-built from a big retailer?
For streaming, yes. Custom builders let you pick quality parts (good PSU, proper cooling, named-brand RAM and SSDs) rather than the cheapest components a volume retailer can source. You also typically get better QC and longer warranties.
How long does a custom streaming PC take to arrive?
It depends. Aftershock offers next-day dispatch on their ready-to-ship range, while fully custom builds from any of these builders typically take one to three weeks depending on configuration and queue length.
Should I go for RTX 5080 or 5090 for streaming?
For pure streaming, a 5080 is more than enough thanks to the latest NVENC encoder. The 5090 is only worth it if you're also pushing 4K gameplay, doing heavy video editing, or working on AI and 3D workloads on the same machine.
