I made a couple of changes. I changed the 8320 to an 8350 since I think it's much better value for money. You can always overclock the 8320 to get to 8350 levels and way beyond. I added a CPU cooler, since stock coolers suck in general. I also added a much better motherboard.I changed the SSD to a bigger one.I changed the overly expensive case to a more sensible one ( but you are free to change it). I also changed the PSU to a tried and tested one. Lastly I changed the RAM to a low profile option, so you won't have trouble fitting it under the cooler(it was also cheaper).
If you have any questions, feel free to ask.
