Try this power supply
. Really, I would buy anything Seasonic made. So go with Seasonic or all the XFX brand power supplies are made by Seasonic. (As well as several other brands) Don't buy the power supply on your second build.
You don't need a 3770K if this is just for games, get a 3570k.
Check out Cooler Masters HAF series of cases. They are big and allow for alot of air flow...hence the name, HAF.
This is a solid Motherboard. Gigabyte makes really good stuff. I would go with something from them or ASrock. I have an ASrock and It is great for me. If you are going to overclock a lot, then honestly you should get a gigabyte. Also look at the UD3H model. Still in the z77 chipset.
I'm not sure why you are stuck on 16gb of ram, but if you get 8 now (which is really the standard for gamers) you can pick up another 8 down the line for 50 bucks. Save the money and step up to a 7970. You will be much happier in the future with a 7970 plus you can get one with 3gb of vram, which MIGHT be very useful when the new consoles come out. I purchased a 4gb card because of this. Only time will tell if I wasted money on the extra vram or not...but you should at the very least get a 7950 3gb.
Check this out.
That is a horrible price for a 120gb SSD. Try to find a Samsung or Crucial M4 120/128. You should be able to find one of those for $99 pretty easy. I got my 128gb M4 for 80 on sale.
My biggest advice for your second build would be to not buy that power supply...spend money on a good one. I don't think I can stress that enough.
