Like 486s draw so much more current than 386s?

There is a very nice case sold by a company named Data Storage Marketing.
It is big and heavy, in both construction and weight, has 8 half height
drive slots, fairly big power supply, and carrying handle on top (in
case you want to make it into a portable :)

Since you have a larger than usual number of drives as well as
more memory than usual, you should consider a larger power supply.

But beware, just saying "we have a 450 Watt supply" does not
necessarily help you. Look at where that power is supplied.

PC Power and Cooling has a 450~ Watt supply which puts out
no more current than the 375 Watt supply on either the 12V or 5V lines (I
can't remember which). In one case, your memory has no more current
available; in the other, your hard disks have no more current
than with the smaller supply. Caveat emptor.

No matter how you divvy it, 450 Watts is a lot of heat!

I found the number for Data Storage Marketing here: 800 543 6098.
They are out in Colorado and seem to be a good bunch to deal with.
