Current lineup:
* Intel i3-2100 3.1G CPU
* ASUS P8H67-M mobo
* 8G DDR3 1333 RAM
* ASUS Radeon HD 6950 2G GPU
* WD 500G SATA3 7200rpm 32M HDD
* ASUS SATA DVD-RW


Question #1: Am I not making a mistake by choosing an i3 CPU? I'm not planning on doing any serious video processing. I figured that it won't be a bottleneck in gaming, so chose a good GPU instead. And I really, really, really don't want to fuss around with overclocking.

Question #2: Am I not making a mistake by wanting a mini-tower? I'm looking at this Chieftec specifically: http://www.chieftec.eu/index.php?id=390&option=com_content&task=view&lang=EN - will the graphics card fit? any other concerns I should have?

Question #3:
What (full-sized ATX) power supply will be sufficient?
