The person offering this collection up for sale is Adam "Kancept" McNutt. The two main items in this set are of course the BeBox and the BeIA web tablet. The BeBox is a dual 66Mhz model, and comes with all the original parts, as well as a few upgraded parts. This is the machine that has built a few of the PowerPC builds of the legendary BeShare, actually.
The BeIA web tablet is also immensely interesting. "Development deck #33, made by Qubit. Everything on the unit works, battery no longer holds a charge. Stylus present. Also including a PCMCIA CF card reader if you want to flash other ROMs that are available out there." A very interesting piece of hardware, and probably quite rare as well.
The set also contains a whole slew of programming books, software releases, and even t-shirts. Whether you're going to bid or not, this is a hefty slice of history.
