Here is my $500 gaming computer. I tried to pack as much performance in this as possible. I included an SSD, 8GB of RAM and a cheap case with some back cable management. Overall it was a great experience. The case was a little hard to work with because of the cheap metal used, but I got by.
Great processor for the money. It does have some trouble in AAA games because of the lack of cores, but overall a great processor.
This motherboard lacks a lot of features, and the bios leaves much to be desired, but you can't beat the price. It has USB 3.0.
This is a great SSD. PC boots up very quickly, and overall browsing through the computer is quick and snappy.
Great graphics card for the money. I love the extra 2GB of Vram, and it has very good cooling. I overclocked this to 1150Mhz core clock and 1630Mhz with a 100 over voltage.
This is a great case for its money. The price definitively shows though. The metal is low quality. There is back panel cable management. The drive mounting mechanism is odd, and the power supply is on the roof of the case.
Great power supply, has not given me any problems so far.
