Q: When I was looking at the description for the Computer Case I'm looking to buy, it said "The PSU, in departure, is at the bottom of the case, for better stability and thermal environment for the CPU." This means it comes with a PSU right? Sorry if it seems like a dumb question I only know basics with computers.
A: Short answer: No, by itself that sentence doesn't necessarily mean that the case comes with with a power supply. They could just be describing where any power supply that you install would be located within the case, since that's a bit different from where the PSU has traditionally been located. Lots of (especially) newer cases have the power supply on the bottom so as to make the case less top-heavy (thus, in theory, more stable), and to provide some separation between power supply and motherboard. The Antec P182 is a good example of that, where the PSU is on the bottom in it's own separate chamber. You can see a picture of that here: http://www.newegg.com/Product/ShowImage.aspx?CurImage=11-129-025-10.jpg&Image=11-129-025-02.jpg%2c11-129-025-03.jpg%2c11-129-025-04.jpg%2c11-129-025-05.jpg%2c11-129-025-06.jpg%2c11-129-025-07.jpg%2c11-129-025-08.jpg%2c11-129-025-09.jpg%2c11-129-025-10.jpg%2c11-129-025-11.jpg%2c11-129-025-12.jpg%2c11-129-025-13.jpg%2c11-129-025-14.jpg%2c11-129-025-15.jpg&S7ImageFlag=0&WaterMark=1&Item=N82E16811129025&Depa=0&Description=Antec+P182+Gun+Metal+Black+Computer+Case Some cases, like the Cooler Master 690, even have it so that the power supply at the bottom sucks in air from a grill on the bottom of the case (the case is elevated a bit off the ground), so it doesn't have to deal with trying to cool itself with hot air from inside the case.
