I have an existing setup that uses four 120G drives in software
RAID 5
under windows 2000, and I learned that it's best to have exactly the
same kind of drives. Mixing WD and Seagate caused problems. Is that
a RAID 5 idiosyncrasy or a windows thing?

I've heard it recommended for any RAID, but I've never had a problem
under
Linux sw RAID with differing brands of drives.

Two drives from different manufacturers that are the same advertised
size may not have exactly the same formatted size. This isn't a
problem when you create an array; the extra space on the slightly
larger drives is just wasted. It can be a problem if you have a
failed disk and the replacement drive is slightly smaller than the
others, however.

Or, create a partition on each drive that is exactly the same size, then
make your arrays with eg /dev/sda1 and /dev/sdb1 instead of sda and sdb.
