I will be setting up a new system soon, probably in time for FC4. In the form factor I want (microATX) and the list of features I need (Socket 939, PCI-express, SATA, gigabit ethernet, USB2.0, FireWire); which would have better Fedora compatibility, one with an ATI RS480 chipset, or one with a nVidia NForce 4 4X chipset?
