Since CyberPowerPC offers full customization of PC, OP can switch out the crappy MoBo with any other in the included list. E.g MSI Z270 SLI PLUS that costs extra $4.
Dell desktops are also good ones to go for. Though, with Dell, it's difficult to replace some components (e.g PSU) since those have different manufacturing than on those that are commonly available, binding you to use only Dell supplied components.
