Gaming PCs Built Without Compromise
Nebula is our flagship range. Every build pairs the NVIDIA GeForce RTX 5090 32GB with an AMD Ryzen X3D processor, 64GB of DDR5 and a 360mm liquid cooler, so you can run 4K at maximum settings with ray tracing left on. Each one is hand-built, stress tested and supported by our technicians in London.
The Nebula Range
Two builds, one graphics card. The Nebula and Nebula Elite both run the RTX 5090 32GB, so gaming frame rates are close between them. The Elite adds more cores, a flagship motherboard and more storage for work that is not a game. Either can be customised before it is built.
A Flagship With Nothing Holding It Back
Plenty of high-end PCs pair a fast graphics card with a slow processor, thin power delivery or a cooler that gives up after an hour. In a Nebula, every part is chosen to keep up with the RTX 5090, so you get the performance you paid for through a whole session.
Browse the range →Nebula or Nebula Elite?
If you mostly game, the Nebula is the better value and gives up very little. If you also render, edit, compile or run local AI models, the Elite is the one that stops making you wait. Tell a UK technician how you work and we will point you to the right one.

Tell us the game and your monitor and we will tell you honestly how a Nebula will run it. Call 0207 096 5008 →Frame rates are 4K averages from published testing of this hardware and our own bench runs. Real results vary with the scene, driver, game patch and monitor, so treat them as a guide, not a guarantee. DLSS, FG and MFG mean NVIDIA upscaling and frame generation were used. Both builds share the RTX 5090, so these figures apply to either.
Inside a Nebula Build
A flagship deserves a flagship build. Every Nebula is assembled by one technician from start to finish in our London workshop, with the cabling, airflow and testing to match the hardware.
- Genuine parts from NVIDIA, AMD, ASUS, NZXT, Corsair and Samsung
- NZXT H9 dual-chamber cases with a 360mm radiator in the roof
- Extended full-load stress testing on the CPU and GPU before sign-off
- Windows 11 Pro, BIOS and firmware updates, and Game Ready drivers set up before dispatch
What Makes a Nebula a Nebula
A flagship is only as fast as its weakest part. Here is how every Nebula is specified so that nothing slows the RTX 5090 down.
GeForce RTX 5090 32GB
NVIDIA's fastest consumer graphics card, built on Blackwell. Its 32GB of GDDR7 gives large games, 3D scenes and AI models room to work.
Ryzen X3D at the Core
AMD 3D V-Cache keeps more game data close to the processor, which cuts stutter and keeps the RTX 5090 supplied with frames, especially at 1440p.
DLSS 4 Multi Frame Gen
AI upscaling and generated frames let you run maximum settings and high refresh rates at the same time, even with path tracing on.
360mm Liquid as Standard
An NZXT Kraken Elite 360mm cooler with an LCD pump display. Three fans on a large radiator can spin slower, so the PC stays fast and quiet through long sessions.
1200W 80+ Platinum
A high-efficiency supply with plenty of spare capacity for the RTX 5090's peak load and for upgrades later.
64GB DDR5 as Standard
64GB of DDR5-6000 means games, streaming software, browsers and creative apps all have room at once. The Elite uses Corsair DOMINATOR Titanium.
Fast, Large NVMe
A 4TB Samsung 990 PRO in the Nebula. The Elite adds a 2TB PCIe 5.0 boot drive with read speeds up to 14,700MB/s.
X870 With Room to Grow
ASUS X870 motherboards with PCIe 5.0, Wi-Fi 7 and spare M.2 slots, on AMD's AM5 platform with a clear upgrade path.
Nebula or Nebula Elite?
Same graphics card, different jobs. If you only game, the Nebula gives up almost nothing. If your PC is also your workstation, the Elite is worth the step up.

Which Nebula should I buy?
If gaming is the main job, buy the Nebula. It has the same graphics card and gives up very little in frame rate. If you regularly render, export video, compile code or run local AI models, especially while gaming, buy the Elite. Its extra eight cores, PCIe 5.0 boot drive and flagship motherboard are all aimed at work that is not a game.
What resolution is a Nebula designed for?
4K at maximum settings, including games with full ray tracing or path tracing. It also drives high-refresh 1440p displays very comfortably, and has the memory and output bandwidth for 8K in games that support it with DLSS enabled.
What monitor should I pair with a Nebula?
To see the benefit of the RTX 5090, choose a 4K panel at 144Hz or above, or a 1440p panel at 240Hz or above. Our team is happy to advise, and bundling a monitor with your build usually saves money.
Is a Nebula ready to use out of the box?
Yes. Every Nebula comes with Windows 11 Professional installed and activated, the latest drivers configured and updates completed where possible. Connect your monitor, keyboard and mouse and you are ready to go.
Can I customise a Nebula before ordering?
Yes. Our team can change the storage, case colour, memory and other hardware on either Nebula before it is built. Call 0207 096 5008 and tell us what you need.
Can I upgrade a Nebula later?
Yes. Both builds use industry-standard parts throughout. The 1200W power supply and X870 platform leave plenty of headroom, with spare M.2 slots and memory capacity for later. We also offer an upgrade fitting service.
How loud is a Nebula under load?
Quieter than you might expect. The 360mm radiator and dual-chamber airflow let the fans spin slower for the same cooling. Under a sustained gaming load it is audible but not intrusive, and at idle it is very quiet.
What warranty comes with a Nebula?
A 3-year total warranty: collect and return in the first month, free replacement of faulty parts for the first year, three years of labour cover, and lifetime UK technical support. Exact terms are listed on each product page.
Do you deliver, and can I collect instead?
We deliver free across the UK, usually dispatching within one to three days. You can also collect from our showroom at 48 Tottenham Court Road in central London, where you are welcome to see a build before you buy.
Can I spread the cost?
Yes. We accept Klarna, Clearpay and PayPal Credit alongside standard card payments. Finance is subject to status and available to permanent UK residents aged 18 or over.
Not Sure Which Nebula Is Right for You?
Tell us what you play, what you make and which monitor you use, and a UK technician will tell you honestly which Nebula fits, or whether something else in our range suits you better. We would rather specify it properly than sell you the more expensive one.
