I've had mainly good but some bad experiences in putting
'huge' drives into old equipment.
Usually, as you say, Linux won't care and will see the whole
drive - you'll probably need to be aware of the 512MB limit
problem with the bios however.
Sometimes though Linux won't get a chance to see the drive
because the box itself won't get past POST with the big drive.
I had this happen to me recently with a 40GB IDE drive hanging
off the onboard controller of an ASUS TX97-X motherboard.
Nothing I did worked, the motherboard just wouldnt boot with
this drive plugged in and set for full capacity. Luckily IBM
drive allowed me to jumper it for 32GB and this worked (Linux
sees only 32GB though of course).
Your machine is probably significantly older than mine and you
may have similar problems.
Needless to say I've never ever come across a problem like this
even with positively ancient computers using SCSI drives :)

[snip description of where drive will live]
Yes, I'd be concerned. I use only IBM drives and the 7200RPM
versions do get extremely hot. I think I know what you mean
when you say the drives are closely packed (no air space
between them) - I'd get a front mounted fan that sits in front
of the drive stack if you can - this should make a difference.
Be aware of course that most heat from the drive stack will be
carried away from the drives via the steel mounting panels -
its up to you then to make sure that air circulates around to
help the heat sink action of the steel case itself.
Best regards,
Craig
