The CM is similar to what I have (the HAF 922) and I love mine. I don't think you'd go wrong with that or the NZXT. Both will flow a fair bit of air and keep everything cool. Personally I'm not a fan of the handles on the Scout, but it does have the side intake that the NZXT doesn't.

To answer your power supply questions though, the 2.x numbers next to the ATX12V denote power supply revisions. As quoted from Wikipedia:

"ATX12V v2.1
This is a minor revision from March 2005. The power was slightly increased on all rails. Efficiency requirements changed. Added 6-pin connector for PCIe graphics cards that aids the PCIe slot in the motherboard, delivering 75 watts.

ATX12V v2.2
Another minor revision. Added 8-pin connector for PCIe graphics cards that delivers another 150 watts.

ATX12V v2.3
Effective March 2007 and current as of 2012. Recommended efficiency was increased to 80% (with at least 70% required), and the 12 V minimum load requirement was lowered. Higher efficiency generally results in less power consumption (and less waste heat), and the 80% recommendation brings supplies in line with new Energy Star 4.0 mandates.[14] The reduced load requirement allows compatibility with processors that draw very little power during startup.[15] The absolute over-current limit of 240VA per rail was removed, allowing 12V lines to provide more than 20A per rail."


When looking at power supplies, you want something with a solid wattage, a fair bit of 12A current, be it on 1 large rail or several smaller rails, and a couple PCI-E power connectors should you decide to run Crossfire or SLI in the future. For example, I have a 700W OCZ power supply with 4 12V rails at 18A each. That SeaSonic has 2 12V rails at 24A each, so if you're not planning on running Crossfire or SLI in the future, it should work just fine for you. I bought mine with the intent of future crossfiring, and it paid off: I ended up with dual 4870s down the road. Newer cards might be more efficient and need less power, someone else will have to chime in on that.
