For gaming 16gb of ram is overkill, but at the same time if its good price 16gb of ram will do no harm to your gaming
I would change the PSU for a better brand one like a Seasonic or Corsair model
I wouldn't bother with a H80 liquid cooler the Bitfenix prodigy can fit a Cooler Master Hyper 212+ EVO in it and it works well (I have one in mine can be a bit tight to fit and works greast)
After some thought.. my new set up is..
1 x Intel Core i5 3570K Unlocked Quad Core Processor LGA1155 3.4GHZ Ivy Bridge 6MB Retail
1 x Cooler Master Hyper 212 Evo Direct Touch 4 Heatpipe Heatsink AM2 AM3 LGA1366/1155/1156/2011 120mm

I went with the cooler master 212 however I was wondering if you are using the same mobo as I plan to.. from what I read, the cooler master 212 series will not fit.
"Basically, this is the ONLY viable Z77 ITX board if you want to have any hope of using a massive air cooled heatsink. All other Z77 boards have a terrible layout and don't allow you to use the larger heatsinks. You can use a noctua NH-D14, phanteks or thermalright archon, and still fit a full sized video card, so there's really no need to use gimmicky closed loop "water" coolers. One catch is, you can't use coolermaster hyper 212 series of heatsinks, because of the cheap and unpadded backplate it uses."
