One more thing, what's the best OS to mine? Does it matter at all?

I am comfortable with Linux, so I'd run Debian on it. Is the linux version capable of same speed as other versions?

Thanks!

Thanks for the reply!

It looks pretty neat and also powerful.

Hello,

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
Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130274

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!
