I've had this Pc for about a year and a half and have never had any issues with it. It can be a little bit slow but it probably just needs defragged and most of my crap removed from it!
I use it mainly for streaming music from my NAS hard drive and watching DVD's in the bedroom so it's never really been put through it's paces and I really don't have a need for it to be honest.
Any questions, just ask.
