Hey guys, I just ordered one of those do-it-yourself kits from Newegg.com and plan on putting together a workstation for HD editing. Unfortunately the kit doesn't come with certain essential parts (video card, sound card, etc.) I was hoping some of you could recommend me some parts that would be compatible with the components from the kit.

Any help would be greatly appreciated. Here's the link to the kit I purchased:
