I've been using a 3010 sff for years now as an htpc and the psu has died; it has i3-2130, micro-atx board; be $30 for new psu--can almost get whole pc for that off ebay--basic unit without i3, ram etc. Or is it worth getting better psu--can get a dynex 400w for $30 and putting it all in a new case so could add decent gpu? Computer runs windows10, streams and otherwise performs well. What do you think, is it worth saving?
