this one with a generic 400W psu (I have a 350W fortron that used to live in it, but for some reason it won't boot with my ATI AIW 9700pro plugged in) I'm in the process of saving money to get some fan isolators (and hopefully some new panaflo fans), and I'm pretty sure my parents are getting me a dremel for christmas if so I'll be able to cut the fan holes out too.
I've got 5 kingwin 2500rpm 80mm case fans, and right now it's louder than my tastes can really handle (fans are modded to 7v, and I have a silencer on my vid card)
