Other than having just a single mechanical HDD in that rig which will be a huge bottleneck in loading times of pretty much everything, it looks very nice.
See if you can squeeze in a 120GB SSD, any will do really, even the cheapest one you can find. You can save some cash on PSU, TX650 will be plenty if you aren't going to SLI in the future.

I was just wondering is the 2x4 ones were compatible with my motherboard, I'm not too experienced but it had
Intel Motherboard DZ68BC
ASUS Motherboard P7P55D LE
ASRock Motherboard 990FX Extreme3
under compatability. Will it still work with my MOBO?
EDIT : Disregard that lol, just did a bit of googling and it should be supported. Thank you for your time.
