Never have or ever will use Cyberpower so not qualified to comment other than to say that you read good and bad reviews for all system builders and not just Cyberpower.
I would not pay the asking price for the computer at your second link, GPU and RAM prices are on the high side atm down to the demand for them from bitcoin/cryptominers and, some folk have seized the opportunity to make easy money and have stockpiled any decent GPUs and are now selling them at a premium, GPU prices are expected to remain high and possibly for as long as the turn of the year, RAM prices are expected to fall slowly but sooner rather than later, I mention this for two reasons, the GPU and 16GB of RAM in the Cyberpower build at your link are what have made the price so high and for gaming atm you can realistically get by with having only 8GB of RAM (2 Xs 4GB sticks for dual channel to work).
Other points of note regarding the Cyberpower build, the CPU while being very good it is overkill for gaming, the PSU is only shown to be a standard 80 plus unit, worse still is the fact that it does not even have a brand name, for $12 more you can upgrade the PSU to an EVGA 600W but that is also only an 80+ output efficiency rated PSU, a minimum for any PC that has even a very basic add on video card should be an appropriately powered and good brand Bronze efficiency rated PSU, btw, the upgraded EVGA 600W PSU can be purchased for as little as $40 here this effectively means that the stock PSU in that rig must cost $28, would you seriously consider using such a PSU in a computer that you were going to charge someone over $1300 for, shocking imo
Will go off and put a parts list together for you, will edit this post if you have not already replied.
NB: I don`t like the way that Cyberpower make it look like you are getting the screen in with the price either.
Edit to add: Dantho parts list
Cost slightly more than the Cyberpower PC and has no keyboard but does have an SSD and much better quality components, including a PSU that has a 10 year warranty.
