I would like to get the price down to $350 - $400, but I feel like I am going to sacrifice too much to get to that range. Any suggestions on Processor, Memory, or MOBO mods to reduce costs and maximize speed would be greatly appreciated!!

I DON'T HAVE ANY PARTICULAR FAVORITES, SO ALL IDEAS ARE GREAT IDEAS.

You might want to go with DDR2 memory instead of DDR3, for the Phenom IIs, it isn't much of a performance hit I think. I'd also check how much shipping is going to cost you with that refurbished Centurion. You might be able to find a Case / CPU combo that will shave off a few dollars, and total shipping cost if you get everything from Newegg.

Any other thoughts? I would like to go with a full size ATX board so that I am not limiting room for upgrades in the future. I will probably go with DDR2, but what about feeling on the other equipment? Will the DDR2 and Hard Drives be adequate to use the processor and video card to its full potential?
