I just purchased about the same... (last night baby) except I got an 9800 Pro, and the Chaintech nf3 board. Can't vouch for anything yet... and my HDD's are going to be Raid 80GB Seagate.
My case should arrive today (you can get it cheaper @ AJump, but long shipping). If you plan to OC, get faster RAM. Something qualified for 250 FSB. Reportively, the Cas doesn't matter as much anymore... I bought the A-Data DDR 500 Ram. Again, I can't vouch, but it's 19 bucks more. I have heard great things on Geil. If you aren't OC'ing, go Via, apparantly their board is superior if you aren't oc'ing nor using RAID.
And for the spicy Radeon, I plan on purchasing the this VGA Silencer,

It should be sweet in our Sanata case. I also went w/ the retail chip, therefore I get Far Cry. I'll give the OEM HS/Fan a chance... if it's too loud then I'll buy something else.
Looking forward to Linux 64, maybe XP64, but Cool'n'Quiet is just awesome... I jumped from the 2400+ Mobile in the last minute before purchasing. I'm using my classic Athy 500 w/ a V3 3000, so I will be happy no matter what I got. >8)
