I'd reccomend fx8320 or an fx6300 if you're building lots of rigs.

I'm all ears, why the 8320? (I'm just building one rig - and I am just gonna do it to support the network - but yeah, I'll take what I can get with Quarks).
Suggestions? (I will use the rig for other things eventually, so probably get a DVD drive, 8GB ram but just on board video - I pay .28 KW/h for electricity, so video card mining is out.)
CPU cooler is a must
Thx
Buy a 4 processor Xeon board.
Don't you see the difficulty? Even that much firepower is NEGLIGIBLE. I think the network hash rate is 4K Mega+
