Pics of my new triple 6990 caseless rig. It's been running with dual 6990's for about 3 weeks now, and I just added a 3rd 6990 yesterday. I also have 2 more Sapphire 6990's coming in soon, and will put those into my desktop rig, which I use everday.
MyOpenPC Stackable case (with rear vertical board removed)
Corsair AX1200 PSU
Is it stable with that 1200W PSU? do you overclock? how much power does the whole system draw with 3* 6990's?
