A:AnswerThe desktop does come with a basic USB mouse and keyboard. The power supply is total 460 watts and there is no 80 plus certification logo on the power supply itself. As for a mouse, I currently use the Razer Taipan 8200 DPI mouse and its pretty comfortable.
A:AnswerActually it has 1x 16gb stick and another stick of 16gb would run you $150-200. Only worth it if you do heavy video editing though you would see across the board improvements using dual channel. I'd recommend adding an m.2 drive for your biggest bang for your buck as a first upgrade.
A:AnswerI can't say 100% but the promotional photos show 2 graphics cards. But as stated in another question/answer it only comes with a 375w power supply. Which I wouldn't think is beefy enough for crossfire.
