Sounds good to me hell a few years ago I had a old IBM 386
One thing though be sure to get HD tune when you setup that machine to check the drives in case there is any thing bad such as spin retry count or re located sector count before moving any thing on to those drives. One thing about older machines is that the drives do go bad if they have received a lot of use during their time. If they got less than lets say 6000 hours each and nothing is in yellow or red then you are good. A typical drive might survive up to 20,000 hours of use before failure. The most that I have seen in person was a old 15gb quantum fireball that had a astonishing 43,000 hours and still passed smart test.
