If you don't know anything about computers I suggest you just buy a computer because you would probably mess something up if you tried to build/upgrade one yourself.
Except when you have a bad cpu cooler.
When I first put this together, I almost turned it on without plugging in the CPU fan power cable.
Make sure you can run all of that on your PSU.
Motherboard may not fit.
Does your PC look like this? I recognize your psu, I'm currently using the same. (Probably buying a new one maybe today.)
