Rhino22 put together a great box for me. Asus K8V SE Deleuxe MB, Athlon 64 3400+, gig of DDR ram, ATI x800 Pro, Serial ATA, Aspire 520 watt PS, Promise SATA Raid chip and Via SATA Raid built into the southbridge, built in gigabit networking, 6.1 surround sound, you name it, this Mobo has it.
$1180 including shipping. This beast is fast!
$875 if you want the standard ATI X600 pro (plus shipping).
BTW - if you are looking for SATA drives, NewEgg.com has the Western Digital Caviar SE 160GB for $98.00 each (OEM).. killer deal. 3 year warranty.
