Yes and for a single HD the performance wont be reduced much.  There are pne
big and one minor gotchas however.

The size of the new HDs is often not supported by the old mobo's BIOS.
Flash the latest mobo BIOS or get a Primise Ultra66/100.

There may be another mobo BIOS bug whereby ATA66/100 mode drives are
improperly initialized.  A HD mfg supplied utility is used to force the
drive to ATA33 mode which solves the issue.
