I have a HP z545 Media Center PC that has been sitting with a bad 250 watt power supply. It is a decent enough machine but I wasn't going to waste my money on a new 250w ps. So I either want a larger power supply that will fit the case without any cutting or else a similar media center case with big power supply that will fit ALL of the guts of the HP wish many vents and slots.
Does anyone have any recommendations? Will only certain watt power supplies work?
