Can some one Check my build?

[detective]

MY CHOICE:
CPU:Intel Core i5-3570K
http://pcpartpicker.com/ca/part/intel-cpu-bx80637i53570k
Motherboard: Gigabyte GA-Z77X-UD5H
http://pcpartpicker.com/ca/part/gigabyte-motherboard-gaz77xud5h
CPU Cooler:Cooler Master Hyper 212 Plus
http://pcpartpicker.com/ca/part/cooler-master-cpu-cooler-rrb10212pg1
Storage:WD Caviar Black 1TB 3.5" 7200RPM
http://pcpartpicker.com/ca/part/western-digital-internal-hard-drive-wd1002faex
Power Supply:Corsair CX Series CX500 500W ATX 12V 80 Plus Bronze Power Supply 140mm Fan
http://www.ncix.com/products/?sku=76035

UNDECIDED WHICH RAM TO BUY, Corsair vs G.Skill (IS 8G enough, shall i go for 16G instead?):

NOT SURE CASE:
Silverstone Redline SST-RL01B-USB3
http://www.ncix.com/products/?sku=72183
Apex PCV-588
http://www.ncix.com/products/?sku=77078
I CHOOSE THESE CASES MAINLY BECAUSE THEY ARE CHEAP WITH 2 USB3 FRONT PANEL AND A External 3.5" Bays.
However, since the motherboard does come with a USB3 FRONT PANEL, it would be alright if someone could help me find a Good C$30-60 ATX Mid Tower WITH USB 2 FRONT PANEL AND 2 External 3.5" Bays that is below 44.5 cm(17.5inch) depth.

Parts Not Required: keyboard, mouse, monitor, speakers, OS, graphic card,DVD
Preferred Website(s) for Parts: ncix.com
Country:Canada
Parts Preferences: i5 3570K+Z77 ATX board +USB 3 FRONT PANEL
Overclocking:Yes, but not always/ not crazy
SLI or Crossfire: no
Monitor Resolution: undecided

I wouldn't go for gigabyte because of low-quality IMO. I don't know your GPU but looking on CPU i would suggest stronger PSU.

Yeah if he plans overclocking he needs a bigger PSU, not too much a 650w is fine.
