I snagged this one off eBay, because it has the plastic and dustmop, the first one didn't. it was listed as Mac compatible, my assumption was White iBook, but iMac makes sense. An iMac is basically a big, stationary laptop.

The desk looks a lot nicer with the Pismo/BookEndz Dock than the ZipMacPlus Case and detritus, but it doesn't nestle underneath the shelf as nicely. Gotta hook it up to the KVM switch.
