they're not TOO bad when you compare them piece for piece. The problem is alot of those sites give you parts you didint want or they dont have the parts you do.
For instance all of cyberpowerpc's PSU's are Apevia, which I dont trust.
Also their motherboard selection always is lacking.
It's always better to build your own if you have even a tiny bit of common sense
