If you have the time, do build your own. What specs are you looking for? Highly recommend 64-bit capable processor and pci-express gfx slot. You can get this in an emachines. the t6520 is a media cnter also, dont know exactt specs but expect to be a good buy, especially due to the back-to-school sale!
Right now I am looking at buying a dell 8400 vs a Velocity Vector SX-V. The two have almost identical specs but the Vector is about $150 more. I kind of want the Vector but am wondering if it's really worth the extra 150.
