You could use two PC cases. One for the mother board and associated
cards, and the other for the drives. That would be a cheap almost ready
to go solution. You could run both cases without the covers to further
dissipate the heat statically.
A water cooled system would most likely require
I think it would be simpler to leave the cover off.

Refrigeration systems tend to use Steel in the condenser coil (the hot
one) and aluminum or copper in the evaporative coil.

Your idea of just leaving the cover off is less efficient than a
well-designed case with good air flow via a case fan, unless you're
going to use a room fan to blow into the open case (or other method
to increase the air flow across the components).

Very interesting, just when we were talking about fanless CPUs, AMD
started shipping Athlon XP SFF processors featuring low power consumption.:
http://www.xbitlabs.com/news/story.html?id=1025602160
Vcore=1.05 to 1.45 V, Max heat dissipation: 35W, price: $116
Well, AMD has introduced a CPU
Heheheheheheheh I've thought about doing that a few times, but to
ventilate my own heat, not the CPU's :-D

Last night on slashdot was a link to water cooling,which leads to many
interesting sites...total kit for $200 on one,also saw a page from a guy
who says the fan can be quieted with out significant proformance loss
by simply lowering the voltage from 12V to 7V...he does it by placing
diods in

Another Backdoor to Root Access

You didn't know that?
There's numerous ways to root a box you haev physical access to.

Yeah, I'd never do it that way, I am always short of outlets. I keep

I know several ways to get root with physical access, but I didn't know
about using lilo like this or how to secure it. This is useful if you have
linux workstations and want to make sure employees/users can't do things
they shouldn't.
Most of us know to set a bios/prom password so users can't

Many new BIOSes can have two separate passwords (supervisor and user)

Well, since for most office tasks, clock speed provides absolutely no

This effectively doubles the size of the cach to 512 KB, as well as data
transfer rate. And this system

The characteristic you're looking to minimize is Thermal Resistance.
I'm no thermo expert though so possibly do some googling on what that is
exactly.
Copper will tend to suck the heat away faster and then the objective of
the fins is to maximize contact between the copper and the air (much

I had over 200 days on my laptop before I reinstalled win98 on it for
the MPEG decoder (coindidentally, the hard drive died within 6 hours
after installing win98...).
Of course, I didn't really do much on it, but it was impressive to be
able to claim I could beat my school's Novell server :)

The reason for large copper bottoms is for even heating (and the reason that only the bottom is copper). Since copper can dissipate heat very well, the heat is spread
across the pan more evenly. It is large to limit warping, provide a reserve, and still provide even heating when cold food is
