You should get the CPU cooler in that list if you want to overclock and keep your CPU cool.
The PSU is fully modular, so cable management should be a breeze.
I also swapped out the motherboard for an Asus, ASSrock aren't really reliable.
Should be grabbing a 500+Watt PSU with a good 12v rail amp raiting. Good brands are Corsair (except CX series) XFX, Silverstone, Seasonic, Rosewill and EVGA. And you will need an after market cpu cooler to properly overclock down the road.
