Requested advice for hardware

[Flomac]

I plan to build a system for the company I work for.
Can someone give me some hardware advice.

Requirements:

- Rack based server
- Space for 4 to 6 cards (depends on the number of GPUs)
(What's the max number of GPUs supported ?)

Required information.

Sagitta Systems

- Prefered server case (in connection with cooling and power supply)
- Prefered motherboard
- Prefered graphic cards (it seems that AMD is preferred - price-speed ratio)
- Prefered power supply (one or more)

Intended for all kind of calculations (oclHashcat/cudaHascat)

Please share (recent) building experiences

Thanks in advance

You need something like this -> Server Rack

But honestly, since some people (including me) are making money by giving advice to people/companies like you, that's as far as I can go here. And no, AMD is not preferred when it comes to TCO. It all depends on what hashes you have to crack.
