Hi Merc,
They have:
200 MHz NSC GEODE GXLV CPU.
32 MB SDRAM, soldered down.
16 MB SANDISK, soldered down.
2 USB sockets.
1 PS/2 socket.
1 CRT socket.
1 RJ11 Modem socket.
1 Sound jack socket.
Typically come with a Power brick, PS/2 Kbd, and a USB Mouse. There are 2 LEDs (and the Power LED) on the front.
Looks like the pads are there for a SODIMM socket to be able to add RAM, but you'd need the socket (ain't cheap) and then hope the BIOS can handle the added RAM.
So unless you are good with a soldering iron, the expandability of the box is very limited.
You be the judge...
