|Hi Guru, the place I would look is ebay/computing/vintage.|
Possibly you may have to accept a different HD make/model, as I seem to recall the PS/2 was sold with optional different capacity HD's.
Here in the UK, these turn up quite often. You do not advise where you are located (city/state) which may help. I was surprised to see how expensive some items are in the US.
Sort by 'time newly listed' and look every few days. You can save a search, such that when one is placed, ebay email you to advise.
Probably be easier/cheaper to look for a complete pc.
Are you sure your HD has died. If the bios parameters have been changed or lost due to battery failure, the disc will not be 'seen'.
Good Luck - Keep us posted.
