I've got a 60GB Maxtor 540x series drive in mine.  I choose the
5400 RPM drive because of its low power consumption.  I can't 
imagine how you could wedge a second drive in there.  There isn't
a whole lot of room;  I think you'd have to do some fabrication
(or use alot of duct tape) to get it all put together.

Now, that said, I *did* lose a power supply a few months ago.
I had put the Qube onto a UPS (cheap UPSes apparently have
a bad effect on the power supply), and I had a PCI wireless card
in it, which was drawing even more power.

Before the UPS and the wireless card, I had some months of 
good service.  My impression (unsullied by facts) is that 
the problem is power, not heat.  A Cobalt engineer suggested
to me awhile back that lots of people just turned off the fan
in the Qube 2 without any trouble.

Good luck,

Kevin
