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+
Wow! Didn't realize they had them. Cost? Computer Models to buy?
And As I said I want to support the network, so profit isn't #1 but breaking even would be nice.
Thx
When the difficulty is that high, why are you concerned about sustaining? It's difficulty is OFF THE CHARTS!
If you really want to sustain, just run the wallet on a high speed Internet connection with static IP which's not firewalled. This way new users can download the block chain easily.
