well... i'd hold on buying these components until the real hardware gurus chime in.. but...

o the power supply is only 250W .. i'd consider an upgrade
o memory... CL5 ?? (i've only ever seen CL2.5 and CL3) lower is better with CAS Latency
o monitors are nice and cheap.. just make sure you're happy with 1440x900

i went to newegg.com and did the same exercise.. i spent a bit more, but i think the rigs are solid (better then what i'm using currently, anyhow)
no monitors included with these:

intel setup:



AMD setup:



i think a page with the current setup of the week would be cool. maybe 3 or 4 levels varying by price and listing performance and realized wow fps and # wows
