CyberpowerPC and iBuypowerPC systems are junk and their support is the worst in the industry. I would avoid them at all costs. I can literally link you to about 50 instances, and I stopped collecting them after that, of examples of poor assembly, poor quality control, completely incompatible hardware installed and shipped together, complete fail by tech and warranty support. On and on. If you buy from them, you have yourself alone to blame.
There are no prebuilt gaming systems that I can recommend, with good conscience, that will be both reasonably priced and will offer something worth the cost and have decent support in the event of any problems. One instance of having to ship your system back to them to fix something and you've already spend more than you ever saved.
If you cannot build it yourself (And I don't know why you couldn't. I know plenty of 14 year olds on here that have done it multiple times, as well as some 75 year olds that I've helped walk through the process) then I'd suggest buying the parts and then paying a reputable builder that you should be able to find locally to do the assembly for you. Honestly, my mom was able to assemble a working system from scratch, and if she could do it, anybody could do it.
The other option is to simply buy a prebuilt system from somebody like Dell or HP, and you'll want to make sure ahead of time that it uses standard ATX components, and no proprietary SFF garbage, and then add your own graphics card and storage, or whatever, to it. Even aftermarket cooling if desired. It's a poor option, but better than many of the prebuilt gaming manufacturers if you dont' want to pay three times what you could build it for yourself AND get better hardware warranties on through the manufacturers rather than the builder.
