1 . Cheaping out on the case would mean it might have less airflow and the case itself might look or feel cheap . Source I built a computer with a ~ 40 dollar case . Performance in game though , the case won ' t affect that at all . 2 . I have a processor in there that can be overclocked so maybe in 35 years you might need to update a couple of parts . That would probably be around 100200 give or take but thats only if you want to play games using super intense features at max settings . 3 . Personally I would not buy one but that is more subject to o p inionrultrawidemasterrace . Huge fan of ultrawide but for you I would say to go with a 1920 x 10801080 p or 1440 p monitor . If you go with a higher resolution then the computer will need to work more to make things run . With a 1070 though this computer would pretty much blow skyrim out of the water . The choice is your so do some research of 4 k vs 1080 p or 1440 p and decide if the monitor would be worth it to you . 4 . I spent around 200 on my mouse and keyboardtotal not each one but you can always pick up a cheap combo set from walmart . Other then that I would say to take a peak at and see if they have anything you like . rMechanicalKeyboards is a good resource if you want to see some of their recommendation for keyboards . Don ' t have anything on mice but you can look some stuff up on the googles and there should be some good resources . 5 . Easier yes but you would pay the same amount for less power . You would spend around 2000 for a computer with less powerful versions of the items in this PC . So if travel is a huge and important part of your computer , try saving up for the laptop or getting on with a 980 or 970 in it . Otherwise , desktop all the way .
