I'd like to build a PC for games mainly, like Overwatch on Ultra, and other demanding titles. I would also use this pic for art occasionally. I just need something that is powerful, reliable and will last a long time. I already have a monitor, and everything you need besides the PC. I don't have a preference for anything since the pic will be under my desk. But please no super bright led things in the case. Please include an operating system in the part list. Oh and one last thing, I don't have the ability to connect to my wifi with a chord, so a good wireless piece would be nice to have.
