i built mine also...p4 1.8 gig...runnin 2 sticks of 512 ddr...with a 60 gig hard drive..radeon card...my best advice to anyone who intends to do the same...be really careful where you get your components...internet sites my look great as far as pricing...but if you have a problem with a cpu or motherboard...it could be a huge problem tryin to get it returned or replaced..they want your money...not your complaints...i recommend buying form a local retailer...if somthing fails...just walk in and talk to living breating human being..walk out with a new componet...may not sound important now...but could be huge later...BUYER BE WARE....BUTCHER
