Animan99: That's the key word I was looking for, thankx!!!!

CritAnime: yes we do, but they usually happen around summer time.
EDIT: I ended up buying this one:
http://www.ebay.com/itm/180556264566?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649The price was right, and I figured I really don't need more than 1 Hard Drive and 1 DVD-ROM hooked up anyhow, though this may still have enough juice to accommodate more as I have been able to boot my machine with a mere 200 Watt PSU, though that was problematic at times which is why I'm currently using my old flaky and very large 350 Watt PSU.
So ya, I think this 300 Watt one will do nicely and it should prevent me from having to make the casing much larger than I had originally intended.
