How's My i5 750 Build?

The Antec 902 case has excellent cooling, and each case fan has its own speed control. This is an excellent choice.

The motherboard you chose is a microATX size. It will work in the 902 case, but it has limited capabilities. You should consider the following Gigabyte P55-UD3L, which is an ATX board and it is only $100:

You should also consider adding a heat sink fan even if you do not plan to overclock because it is quieter and better at cooling than the Intel heat sink fan. The Hyper 212 is only $30:

I assume you have a CD / DVD drive and an operating system.

The rest of your build looks fine, and it is about the best you can do as far as performance / price ratio for an Intel build. Good luck.

The one thing I would change would be the motherboard. I haven't had good long-term reliability luck with MSI. Here's a very nice CPU/motherboard/GPU combo:

The 700W PSU is major overkill for a single GPU system. The 500W version of that PSU would be plenty.

OCZ ModXStream Pro OCZ500MXSP 500W $59.99 - $20 MIR

Here's a couple more combo deals that might interest you:

The above motherboard is great because it uses an upgraded CPU socket and has SATA 3.0 and USB 3.0 support.
