I picked up a couple of these devices... I'll try to take some pictures later this week and get them posted.
The device is running a 2.0.36 linux kernel and is basically a modified version of RedHat 5.2 running Samba, I made some quick config changes by pulling the disk and was able to put a couple of files into a samba share on the device and mount it from my laptop.
There are no ISA/PCI slots, nor is there video onboard... catting /dev/pci does show that there is a pci bridge on the board, as well as video, but i'm not a hardware guy, so I have no clue what to solder where to get it to work.
