Case looks fine, enough fans, the power supply looks like it has enough watts.
MOBO - I have that one and its been running just fine for almost a year.
Graphics Card - again, that's the one I bought and its sweet.
Processor - this is going to sound very odd, but that is the one I have as well. I would go with a different one - a little up or a little down because it benchmarks (and runs) slower than it should. Wish I would have done my research on that one but oh well. = )
The processor was easy to install, I usually have to wrestle with them a bit.
HDD looks good, the 32MG cache and SATA will be a fast drive. WD is usually good.
Memory - I love OCZ memory, it runs cool and it performs. Crucial is always a good bet, as is Patriot. I don't know anything about the G.Skill.
I've heard alot of people say they bought Kingston and it wasn't a good choice. Problems seem to run along the lines of it doesn't last long, it didn't work in the first place, and its underpowered. I haven't used it.
Last but not least..............if fan noise bothers you, get another Heat Sink Fan. The one that comes with the processor is noisy.
I've been very happy with this Arctic Cooling Freezer 64 Pro W/ PWM Fan.
its quiet and my processor temp usually runs around 29C.
That's all I know.
Good luck with your build!
