I have this HP slimline PC lying around for couple of years and when I wanted to revive it and give it away to friend, I noticed that the SMPS is not working and wanted to buy one. Since the cabinet is slimline the regular SMPS does not fit. The slimline SMPS is either not available easily or is priced exorbitant in online. Is there any place I can get a slimline SMPS for cheap or do I need to completely knockdown and assemble existing one to a new cabinet?
