The machines we run for you
The machines we rack and run for you. Bitcoin ASICs, prebuilt GPU servers, and open-frame builds. Prices below are illustrative market estimates, not live quotes.
Bitcoin ASIC miners
Purpose-built SHA-256 machines for mining Bitcoin. Efficiency is the number that matters most, since it sets how much you pay in power for every terahash. On our locked $0.050/kWh, even older units stay profitable.
Daily rev and profit are calculated at a $100,000 Bitcoin price and a 996 EH/s network, on power locked at $0.050/kWh. They move with the market.

Prebuilt GPU rigs
Rigs you can buy ready to run, the kind sold as vendor workstations and servers. They arrive assembled and tested, so they go straight to work renting compute to AI and rendering loads. The densest SXM servers (8x H100, A100) come online with our liquid-cooled buildout. The air-cooled rigs run today.

How buying works
Anything you buy goes through us. We source it, document it, warranty it, and rack it correctly, so it is covered under your agreement from day one. There is a flat 7% over our cost on any hardware purchased through us, the same transparent markup as the power. You are always free to bring hardware you already own instead. Either way, you own it outright, physically and legally.
We buy direct from trusted manufacturers and authorized distributors, never grey-market resellers, so you get new, warrantied units at the real price. And because the markup is a flat 7% over our actual cost, you can see exactly what we paid. Nothing hidden in the hardware, just like nothing hidden in the power.
