If you get an nforce4 motherboard, which supports pci-express, you will probably end up having to spend 90 bucks on a 24-pin psu. While this is not a bad thing and allows for future upgradeability, you probably do not want to spend so much on something that is not very important in your case. Also, most pci-express motherboards do not have onboard video, forcing you to buy a pci-express videocard, which tend to be exspensive. I would recommend a board like this:http://www2.newegg.com/Product/Produ...82E16813138242
because it has integrated video and audio, but is also upgradeable to an agp card if you decide you need some extra power.
