I'm scaling down and selling one of my Bitcoin mining rigs, bought new and only run for two months. Everything is in great cosmetic and working order, fully assembled, all software installed, ready to mine.

The 3 Sapphire 5830s are clocked 850/300@1.063V. I can reset to factory(800/1000@1.163V), if needed. Cards have been run at 70C or less; currently run at 60C in a warm room. The system draws ~400W at the socket. Ubuntu 11.04, SDK 2.4, Phoenix + Poclbm.

With Phoenix+phatk, the cards mine completely stable @ 267MHash/s each (800MHash/s total). A lot of people seem to be getting 300+ out of each card, but I opted for less wear and power usage, on mine.

System cost was $900 new. The case can fit four double cards at once; the motherboard supports 6 cards, with riser cables.

I'm asking USD $699 or best offer, insured shipping included to US only. I will, of course, accept(and prefer to be paid in) the current equivalent amount in Bitcoins.
