If I were new to the scene I'd be hard pressed to think those were both mITX cases.
*sigh* Tempted to just spend another $600 and go an Athlon II X4 860K and a 750 Ti to replace my aging A10-5800K, which I haven't even bothered OCing yet. Even if I did OC it it would still be a weak performer.
I don't know how well a 4+2 phase would take the Athlon. I'm not sure if I would be able to hit 4.5GHz down...
