My PC is part of my bread and butter that is why I do my best to take care of it. If money permits, I will buy him (my PC is a guy, LOL!!) additional computer memory since I am also more into graphics manipulation and digital scrapping. Aside from that, maybe a PC vacuum will do to help get rid of dirt clogging his internal paraphernalia and the keyboards.Love your PC and it will love you back with years of great service!!
