37 open-source models · benchmarked on every build

Stop renting. Start training.inferring.rendering.creating.

Multi-brand AI workstations — from 128 GB unified-memory cubes to 8×H100 liquid-cooled monsters. Every unit ships with the open-source model stack preinstalled: Llama, DeepSeek, FLUX and Wan run on day one. And we'll show you the month your machine pays itself off against RunPod.

When does your machine pay for itself?

Same GPUs, same workloads — the only difference is who owns the silicon. Compare against live RunPod rates and see your break-even date.

Own Rent on RunPod

Rent = RunPod on-demand hourly rate × GPUs × your usage hours. Own = purchase price + electricity at your rate. RunPod rates updated Oct 2026 from runpod.io/pricing; adjust the sliders to your real workload. Taxes & shipping excluded.

Every build carries a 3-year parts & labor warranty with advance replacement on workstations. Liquid loops serviced by certified techs.

Payback, quantified

The break-even calculator on this page uses real RunPod rates. We'll tell you the month your rig pays for itself — before you spend a cent.

05 — Questions

Everything people actually ask

Which machine should I buy to run 70B-class LLMs?
Llama 3.3 70B at Q4 needs ~42 GB of VRAM. That means the Corsair AI Workstation 300 (96 GB allocatable) as the entry point, an RTX 5090 build like the Element 9 Pro (32 GB, runs the 8B–32B class beautifully), or the Bizon G3000 with 4× RTX 5090 for FP16 speed. The Model Matrix lists exact requirements per model.
How accurate is the break-even calculator?
We use RunPod's published on-demand rates (Oct 2026) for Secure and Community Cloud, multiplied by your GPU count and usage hours, minus your electricity at your own $/kWh rate. It's an honest planning tool, not marketing math — taxes, shipping and idle days are excluded, so treat the result as a conservative midpoint.
Do I need a 30 A circuit for the big Bizon rigs?
The ZX5500 draws up to 2.2 kW and the ZX9000 up to 2.8 kW under full training load — a dedicated 20 A/230 V or 30 A/120 V circuit is recommended. The liquid-cooled chassis are surprisingly quiet (~45 dBA), but plan your outlet before the crate arrives. Everything from the Corsair 300 to the iBUYPOWER towers runs on a normal wall socket.
What's the return policy?
30-day no-questions returns on unopened units; 14 days on opened configurations with a 10% restock fee, minus any damage. Custom Bizon multi-GPU builds are final sale once the liquid loop is assembled — that's why we make you confirm the config twice. Full terms are on the legal page.
Can you add a GPU later?
Yes on air-cooled towers — the iBUYPOWER Threadripper PRO and Bizon G3000 leave slots, PSU headroom and PCIe lanes for a second (or third) card. The Corsair and ASUS cubes use soldered unified memory and cannot be expanded; that's the trade for the size and silence. Water-cooled ZX builds are expandable only at the factory.
How do payments and shipping work?
Checkout is handled by Stripe with 3-D Secure; we never see your card. Free insured freight in the continental US on everything, double-boxed with GPU braces. Worldwide shipping quoted at checkout for the cubes and towers; multi-GPU Bizon rigs ship via freight forwarder of your choice. Tracking within 24 h of dispatch.

Your GPU hours are compounding either way

In someone else's datacenter, or on your desk. One of those builds equity.
