I'm thinking of building my own computer for when I go off to school next year, and I've decided that the A64 route is looking pretty nice (3200+ seems cost-efficient), but all of the motherboards I'm finding for the 939 chipset have 10 USB2.0 ports, with 4 designated for the rear. Now does this usually leave 6 for the front? Or 4 front, 2 inside? And what purpose would anyone have with usb or firewire ports on the inside of a case? Here's a list of what I could possibly get, but I have no clue what I should get for a case. Anywho, here's my parts list so far:

Any suggestions/answers to any of my question?

If your just looking for more USB ports you can always buy the little boxes that let you expand one USB port into 4 or more and mount the box wherever you want. I have a 4 port and 3 more on the back. When they say inside they are probably referring to the ports on an expansion card that you plug into a PCI slot. Most modern motherboards have at least 2 on the board, and most cases have them on the front.
