We have a somewhat older computer - it's not archaic but it's not
"new".
We currently have a - newer than other bits - AOpen Ax34 Pentium III
FCPGA 133MHz 4xAGP ATX *stops to take a breath* Motherboard, and
roughly 40GB worth of disk-space between our two hard drives.

It is almost full and we want more space... when I phoned the store,
they said that our motherboard would not support any more than 40GB
worth of hard drive, so I have two questions:
1. Were they telling the truth?
2. If we can't buy a larger hard drive, will we be able to hook up an
external hard drive to get a bit more storage space?

We are debating getting a new computer, but as this one still functions
perfectly well, it seems like a waste if all we need is more disk
space.
