I know your budget is roughly under 1,500 dollars, but this is what I would build. If you can mod yourself. If not, buy a Dell like Kapt. Crunch says. The links below will have your games drooling for action. And, you can always add memory later if you only want to use 8 or 16 Gb now. I don't know what GPU your camp is, so I put both scalable link interface and crossfire options. And the PSU is single 12v rail. The case is mid tower. And you have the option to mount a radiator on top if you choose to go water cooling. Sometimes the full tower cases are too massive, so you can get by with a 0mid tower. 
  
This case probably is a bit over 2,000., but like I said you may change your GPU or Memory. I would definitely keep the SSD. At 256 Gb, you could probably install 10 games or more. Use your old HDD for storage. And just game on the SSD. You can always add another later. 
  
Have fun... Once you start, it don't stop.
