cyberpowerpc cut a lot of corners.
 


First rule of buying something, check on it before you buy it not after, going right to the cutting before measuring is not a good plan.

Almost any pre-built (not on discount for something discontinued) will cost more for the same or worse parts than something you put together yourself. The cheaper computer makers like Cyberpower by default use cheaper parts with often lower reliability. The power supply is often a big issue. If you customize the system on their web site you can chose better parts, but again it will be more cost than if you just buy the parts.
