Hey all. I'm helping a friend of mine build an Athlon X64 dual core system. I have a few questions... and I know this is a Mac site but I also know that mac users have the best taste What is a good, solid and clean looking computer case to use for this type of system. Also, is DDR2 only Intel or are their motherboards for X64 dual cores that use DDR2 as well? It has been awhile since I have done this so I need a little macrumors help haha. I trust everyone's taste here so let me know what you think. Thanks!
