I am looking to build the best possible rig for a rack mounted server, cost is secondary.
What I've been looking at is this:
Video card: GIGABYTE GV-R699D5-4GD-B Radeon HD 6990 or similar
Rack case: http://www.plinkusa.net/products/4220-6.jpg
And the rest as needed (quality 1200W PSU, an SSD and 2GB RAM).
My first question is, is this feasible? Can I put these components together in a rack in some datacenter and have it running a mining operation all the time?
Or is there some better way of using a 4U or 6U space for mining?
My other concern is heat. Sandwitching 3 video cards that run full load all the time will probably generate intense amounts of heat - should I be worried, or will the case with the 6 fans take care of this properly? I'd hate to have the middle card burn out after a couple of days or weeks.
My last question, is a 1200W PSU (or 1350W) enough for these 3 cards?
Thanks for any replies!
