Case on = more heat, but ventilation works.

Convection doesn't work all that quickly, especially compared to air circulated by a fan. If the case is closed, air should circulate up the case (past the cards, past the ram/cache, past the drives, past any voltage regulators on the motherboard), through the power supply and out. The general temperature in the case may be higher, but the hot spots will be fewer, or at least cooler.
If the case is open, the CPU and the power supply (and anything else with a fan blowing on it) will still be cooled. Everywhere else, the air will stagnate (or just move very slowly), your hot chips will waft heat up towards your hot hard drives, and your hot hard drives will just get hotter. While your CPU may register a few degrees cooler (as the fan can blow air from the room across it), but nothing else gets much airflow, so the other $1500 of your $2000 system suffers.
ATX PSU fans that blow in on the CPU are okay for a desktop IMHO, but those don't tend to be heavily expanded. For a tower, you should have as many or more fans blowing out the top back as you have blowing in the front, especially if you have a self-cooking hard drive without a fan on it.

Fahrenheit 451 just doesn't have the same impact any more since the CD-R, though...
The full and server towers in the Extra series *are* wider, and I think it improves the ease of messing with the guts quite a bit. But they're not two drives wide. For that you need an expensive RAID enclosure which has no room for anything but drives.:-(
(Found a use for the 5.25" bay above the power supply? Or did you get the 7890?)
The ability to make a case that looks cool is a matter of exteriors. If SGI and Apple let other people use their case designs, there's no reason the factories that made them couldn't put SGI/Apple outsides on an AT/ATX compatible frame, save for FCC Class B RMI emission concerns.
The (vaguely related) thing I really hate is SCSI cable makers who make their cable plugs such that you have to run the cable to the top of your case, then down the bays--or alternately, have only a between-drives length of cable between the host adapter and the first drive. Ecch. Plug it in the right way (and probably waste a plug), or plug it in backwards and probably waste a plug anyway. What a choice...
Check out Addtronics' "extra" series full tower or server tower at http://www.wco.com/~addtron/index.html. I have a 6890a, and like it quite a bit; it looks like the '91 and '92 series cases are the same as the '90 series intenally, but have nicer looking fronts. You can put fans in all the usual places plus blowing sideways across the 5.25" exposed drive bays.
And if you're reading this, you definitely want the casters. They give you the ability to pull out your case much more easily (or put it out of the way where it goes much more easily)! You probably want them even if you never close the case...
learn and grow from it. The best thing that college can do for you, if you approach it right, is to get you into the habit of thinking. Working so hard you can't think, or doing lots of work without thinking about it, is not the point (though some profs give homework like that anyway)...
The next best thing a good education gives you is the opportunity to explore other things. Really. After CS, and the math prereqs I needed to get the Combinatorics class the CS major required, I got the most credits from Philosophy and Religious Studies. For the MS, my favorite area was operating systems, but I took everything from verification to real-time and embedded systems.
Thirdly--but strongly feeding the first and perhaps the second advantages--the maturity the whole experience can give you, especially when there's a thesis at the end of a degree. It's a different kind of maturity than living on your own and having to pay for your own food and housing, but it's there nonetheless; I give more importance to a good BS than to an MS without a thesis.
Lastly, something you can't necessarily get from college but can definitely benefit from: the artistic or intuitive approach. Computer programming is definitely an art as much as a science, with many good ways to accomplish a given task and strong impact of style. A strong intuition can turn general understanding into an answer very quickly, incorporating more factors than you have the brainpower to conveniently analyze by brute logic. You still need the reasoning ability, as there's plenty of stylistically beautiful drivel in the code base, and intuition is as quick a route to a wrong answer as it is to the right answer.
None of these--especially the intuition--are things that just happen to you by the time they hand you the diploma...but college is a good place and time to pick them up.
If I were them, I'd push my expensive, profitable chips into the higher-resolution processes long before I'd push memory, which is still priced fairly low (even the 128M PC100 ECC SDRAM has come down to $200 or so).
Have the memory makers finished getting rid of their stockpiles yet?
Screw Intel? No thanks. Down with AMD.

My K6-300 (not the K6-2 you gripe about, alas) has been up for 20 days, since it came back up from a power failure that outlasted the UPS. Matter of fact, the previous reboot was due to another power failure...
