Additional Comments: (e.g.: Need to have a window and lots of bling, I would like a quiet PC)
I've specced out a system, which I will list below. I think it will do what I need, but I wanted to double check it with the Tom's crowd and make sure I'm not doing something dumb

This system MUST have 12 NIC's in it at a minimum. It will be running linux 24/7 and will not need any graphics capability besides running gnome to manage some terminals and things like that. This system needs good PCI-e performance for the quad NIC's and a decent amount of storage for the packet capture files. That's really all it needs to do.

I would appreciate any comments about this build. I don't want to mess this up. Thanks!

Hello rensai;

You didn't mention the technical requirements for the quad NIC's. PCI-E x4 slot? x16?

Some alternatives:
GIGABYTE GA-Z68A-D3H $120
With the Z68 you won't need the video card - uses the CPU's IGP - which free's up a PCI-e x16 slot.

750W PSU is vastly over provisioned. SeaSonic S12II 430W PSU $72 is more than you'd ever need.

Hyper 212+ CPU cooler and AC MX-4 thermal compound not required. The CPU won't be running much above idle.

What's the reasoning for the mix of 2TB & 1TB HDD? OS & Programs on the 1TB and data on the RAID array?
