I would suggest maybe this
Athlon 64 3000+ OEM
250GB Seagate SATA drive (instead of the WD 74GB Raptor)
1GB OCZ PC3200
sony black floppy drive
Windows XP Pro
whichever keayboard, mouse and monitor you like. if you get an LCD, make sure you get one with at least a 16ms response time, or fast motion will look bad. 16ms is descent, 12ms is good, 8ms is better.
you don't necessarily have to get them from monarchcomputer.com
don't get antivirus, and don't get Office if you have it already. you can install freeware antivirus programs which are much better, such as Antivir
, Avast, or AVG. I use Antivir and it is really good, much better than Norton.
and make sure you grab the free promos. if you don't like them, you can always sell them to someone (except the napster one)
