I sold my Apple IIGS around the year 2000 for $600 on eBay. Buyer spent an additional $600 for shipping from Canada to California. The buyer was getting it as a gift for a friend who was retiring from Apple and worked on the Apple IIGS.

A quick scan of eBay today is showing $1,200 to $1,800 for an complete functioning Apple IIGS. If he has 1,100 computers, I can see him getting to $23,000-35,000 pretty easily.

Very interesting. I have three complete ][gs "Woz" editions sitting in storage somewhere, that I rescued from a school computer lab where they were being thrown out in ~2004. I also snagged the Macintosh that was used as the server for the network, and all the backup media that I could find. There's a copy of Oregon Trail in there somewhere, that I played in school :)

Maybe I should find them...

I read it as, he owes money on a warehouse, and if he can't pay that debt the contents will be seized and likely destroyed.

Why not donate the stuff if he can’t afford to keep them?

If the warehouse has been foreclosed on, there may well be a demand of back-due rent before he can get his property. This is not an uncommon situation. It depends on the contract signed, but the owner of the warehouse may very well now have possession of the complete contents until back-due rent is paid. This is very common in rental storage units in the US, as well.
