I happen to have a Phenom x4 875BE, and I was looking to get back into system building after a long hiatus by building around it. I've come up with a partial parts list but I'd really appreciate filling in the holes.
Intended use: Gaming. Software Development. HTPC functionality (it'll be hooked up to a TV).
And just to be clear, it's an AMD build!
Finally, I live in Japan so I plan to troll Akihabara for parts once my list is finalized.
