Cyberpower PC makes great PCs. Why? Because you can pick all of the components (exception... HDD brand). It's a great idea and they can often build cheaper than you can build the same thing yourself. If you don't necessarily love tinkering with hardware, but know which hardware you want, it's a great way to go.
Personally, I wouldn't get the paint job, but if you're a huge fan and want to show it, go for it!
