What is the build being used for? I say drop the 2600K (as pairing it with a motherboard that prohibits access to the multiplier defeats the purpose) to the i5-3450, and then upgrade your GPU from the 6670 to a Radeon 7850. And get a full ATX board with a full ATX case - your expansion opportunities will be extremely limited.
