Compatibility shouldn't be too much of an issue with a system assembled with new parts. Things to watch for:
Processor socket must fit that of the motherboard. Probably for you, it will be socket LGA 775.
Check the motherboard (mobo) specs; it will use either DDR2 or DDR3 RAM.
Virtually any mobo you pick will have SATA connectors on it. Make sure you get a SATA hdd.
Optical drive can be either the older IDE interface or SATA (SATA recommended).
Finally, the nVidia 9600 should have a pci-express x16 or pci-express 2.0 x16 interface. Motherboard should have that too. (pci-e original and pci-e 2.0 are cross-compatible.)
Never played the games you mention, so I can't say how well this system would handle them. I would recommend 4GB of RAM, though, and a 250 or 320 gigabyte hdd. Finally, I'd recommend you purchase your components from Newegg. They give a ton of info about each component, so finding out what's compatible shouldn't be much of a problem there.
If you can list specifically what components you want to use (preferably model number) I can tell you if they are compatible. (No money-back guarantees; we're all human.) 😉
