Yeah, yeah, I've ordered yet ANOTHER machine:
Abit NF-M2SV GeForce 6100 Socket AM2 Motherboard
AMD Athlon 64 X2 4400+ Socket AM2 CPU
Crucial 1024MB PC4200 DDR2 533MHz (X2)
Seagate 250GB Serial ATA w/NCQ 7200/8MB/SATA-3G
Power Up Silver 5511 ATX Mid-T Case w/450w
All for $199 after $30 in rebates. Note that there's no CPU heatsink/fan, no OS, no CD/DVD burner, and no vidcard (although there's an integrated one on the motherboard, which may get me through the testing/burn-in phase).
I've just ordered an Arctic Cooling Freezer 64 LP CPU Cooler for $25 from Microcenter. I'll order a CD/DVD burner in another week, and within the next month, I'll install a new vidcard. I don't know what OS I'll utilize yet...maybe Linux, but more than likely Windows (only I don't want to buy Vista [or XP, really]).
At this point, the barebones I ordered last year is still the better computer, but I spent quite a bit more for it. Until the new one is up and running, I'm also using its 2gb of RAM in the older computer, for a total of 3gb of RAM (COD4 flies during loading!).
This is the deal I saw on Tigerdirect.com that made me purchase this machine.
