Antec Three Hundred Black Steel ATX Mid Tower Computer Case

Western Digital WD Blue WD5000AAKX 500GB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive


GIGABYTE GA-H61M-DS2 LGA 1155 Intel H61 Micro ATX Intel Motherboard

Intel Core i3-3220 Ivy Bridge 3.3GHz LGA 1155 55W Dual-Core Desktop Processor

Microsoft Windows 7 Home Premium SP1 64-bit - OEM

PNY Optima 4GB 240-Pin DDR3 SDRAM DDR3 1333

still looking for good graphics card would this work?(sapphire Radeon HD 7770 Graphics Card)

ask me if you need more information on any of these to see if they would all work together. im so lost.. but ive gotten this far haha

oh and this power supply: LOGISYS Computer PS480D-BK 480W ATX12V Power Supply

i would like to hear your opinion on these brands, my choice of things to build this. (my budget is $500 and im cutting it very close right now)

the qpu is fine but do not skimp on the psu get one from either seasonic corrasiar or XFX because they are some of the best brands for psu and if u skimp on them u can blow ur entire system 

I'll see what I can do

What do you intend on doing? here's one for $520.

the psu is shit.(Logisys)      Under $450 if you want to spend 50 more get a better mb

the a8 cpu will run just a little lower than the i3 but you can oc the a8 and get better preformance

He also needs the OS included according to what he has.
