IMHO:
- you don't need two SSDs. You can replace the second SSD with a large (2TB or more) hard disk.
- the 750W power supply seems to be a bit over the top. The CPU is rated for 66W and the video card for 300W and these are the two major power sinks. The only advantage of a more powerful PSU is that if is less likely to switch on a noisy fan. But a 500W PSU is more than enough.
- unless you are a gamer you won't get much from the Graphics Card. The CPU you have has an integrated graphics processor.
- is the RAM in one card or two? With two cards you can sometimes benefit from increased memory bandwidth. If I were to increase something in this setup, it would be the RAM: 16GB is good, 32MB is better

- I've read that the stock fan/ventirad that comes with the CPU isn't very good. There are very efficient (and silent) OEM ones, and this isn't a very expensive part.
- an itemized list would be a bit more useful...
