Is this a good PC? Any suggestions?

Solution
You don't need to change the GPU. You can if you want. The only thing that needs to be changed is the PSU. Thermaltake has hit/miss quality units. Try to get an Antec, Seasonic, or XFX. You may have to pay a little more but it's worth it for a reliable unit.


But that mobo has no 3.0 headers, also there is a lot of compatibility issues with that build.

There is an Aztec about the same price but 500w, is that enough?

 

Is Lenevo/e-vga/silver stone? I hear good things about them
