PC that will last

I need help building a PC that I'll be able to use or at least upgrade for a long time into the future. 

I mainly use my pc for school and gaming. I do not have access to ethernet so a Wi-Fi enabled motherboard is a need. I'm looking for something that can handle graphically intense games at a stable FPS. I already have an O11 Vision and an Arctic Liquid Freezer III AIO but anything else is fair game. 

Thanks peeps!
