Help building a dual Xeon workstation

I've got a shopping cart going but need some advice on important decisions

I added

2x Intel Xeon E5520 Nehalem 2.26GHz LGA 1366 Quad-Core Processors
1 ASUS Z8PE-D12(ASMB4-IKVM) Dual LGA 1366 Extended ATX Server Motherboard

and OCZ Gold 12GB (6 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 Memory

So, with this mobo,

Will it take pretty much any PCI express video card? And Sound Card?
What kind of power supply do I require?
Is it essential to shop for an Extended ATX Case?

The Processor comes with no heatsink, got any ideas what to shop for?

Really need some advice before placing my order.

Thanks

  3. what are you going to be building this system for? it will give us a better idea of what hardware to recommend for you
  4. I am following this thread because I have the same motherboard I am building up. My main concerns at this point are:

    1. finding a 4U rackmount chassis for this big board-- lightweight aluminum preferred.

    2. Finding a good PSU to support the dual CPUs, memory, and multiple CUDA GPUs

    3. Finding a liquid cooling system. I have never used liquid cooling to this point.

    Please share your findings with me!
  5. Have this company build your workstation computer and they have a dual xeon with water cooling: www.titanuscomputers.com
