don't wast your time trying to grow in a computer case.

what are your worries about fire? i've stuffed 18+ 23W CFLs in a cardboard box without any problems. if you plan on going with HID then you will want adequate cooling, but unless the bulb is making consistant contact with the box you have no worries about fire, unless you jack up your electric wiring in which case wood or cardboard could possible go up in flames.

just use common sense.

good growing!
