It's just personal opinion, I just built this new system of mine using a MAXTOP case I got from newegg.com
It had 2 fans built into it and I added 3 more because of the heat generated by my P4.
My reasoning for getting a P4 instead of an Athlon XP, (even though I am an AMD fan)was because of the 400mhz front side bus speed.
I'm running an MSI 845-ARU Motherboard, I chose it because it has 8 built on USB ports (4 USB 2.0, 4 USB 1.1... 2 in the front of the MAXTOP Case, 2 on the back of the board, and the 4 2.0 ports on a bracket.)
If you're going to go all out, having 512k L2 Cache like the P4's have is a great thing...
Anyway, these are just my personal preferences for the latest machines I have messed with..
