For those who enjoy big cases (like me), then you'll want to see if the Antec SX-1240 Case is for you. here's a snip:

"The Antec SX-1240 is part of the company's "Performance Series" and at 26.4" high it's no slouch. It comes with their PP412X 400W which meets the ATX 2.02 spec, so it is compatible with both the Pentium 4 as well as the Athlon 4 (which is currently only available in a mobile solution). This is an important feature to look for if you are in the market to buy a new case because it will extend its useful lifetime greatly."
