I built my rig 1 year ago approximately. I think I started in early August after I got back from a trip to LA but I was missing a lot of things like a good monitor and a 7800Gt. My 7800GT came on my bday I remember (Aug 25th), and that was when my build was complete.
Specs were 3700+ San Diego @ 2.6ghz, 1gb OCZ VX 2-2-2-5, Seagate 7200.8 250gb, BFG 7800GT OC, Viewsonic VP191b, blah blah
Upgraded to Opteron 170 and 2GB of RAM and a Raptor in spring/early summer. Ready to upgrade with another 2x 7200.10s very soon. Seagate replaced my 7200.8 for a 7200.9 in June (RMA) and I got an eVGA instead of a BFG (sold) thru ebay.
