Overview
Local AI, without the cloud bill
The Ultra 9 AI Workstation pairs NVIDIA's GeForce RTX 5090 and its 32 GB of GDDR7 with Intel's 24-core Core Ultra 9 285K. That's enough GPU memory to run 30B-class language models and full-precision image models entirely on the GPU, privately and with no cloud bill.
Inside a Fractal Design Define 7 you get 64 GB of DDR5-5600, a 2 TB PCIe 5.0 NVMe SSD, a be quiet! Silent Loop 3 liquid cooler and a 1000 W 80 PLUS Gold power supply.

Use cases
What you can do with it
Everything runs on the machine under your desk: no per-hour bill, no usage caps, and nothing you type or upload leaves the building.
A private AI assistant
Run open models like gpt-oss, Qwen and Llama for your team. Prompts and data stay on your network.
Chat with your documents
Point a local model at contracts, manuals or code and ask questions, without uploading files anywhere.
Generate images
Create product shots, concept art and marketing visuals with Stable Diffusion and FLUX.
Fine-tune and build
Train LoRA adapters on your own data and prototype AI apps with CUDA, PyTorch and Docker.
Model fit
What AI models can the RTX 5090 workstation run?
GPU memory (VRAM) decides which models fit. This build has 32 GB, so every bar that ends left of the line runs fully on the GPU.
Approximate memory for the model plus a working context. Larger models can run partly on the CPU and system memory, much more slowly.

Same case, cooler and build process. The GPU sets which models you can run; the CPU and memory set how much else it handles at once.

What can I run on it?
Check the model list above: anything marked “Runs on this build” fits fully in GPU memory. Working with something that isn't listed? Ask us before you buy.
Which operating system does it come with?
Windows 11 Pro, set up with current NVIDIA drivers and tested before it ships.
Does it need special power or cooling?
No. Every build uses an 80 PLUS Gold power supply (850 W or 1000 W, depending on the GPU) and runs from a standard household outlet. The CPU is cooled by a be quiet! Silent Loop 3 liquid cooler inside a sound-dampened Fractal Design Define 7 case.
Can I upgrade it later?
Yes, but contact us first. Hardware installed after shipment isn't covered by the warranty, and we can confirm which parts are compatible.
How long until it ships?
Each system is built to order, burn-in tested for 48 hours and ships in 7–10 business days. Shipping is free.
Do you sell to businesses?
Yes. We accept purchase orders and GSA, offer net terms, and quote multi-unit orders. Request a quote.
