  Before I go hauling all those little Torx screws out

 have proper Torx bits, unlike the last person to be inside it), can
 anyone point me in the direction of the CMOS battery?
 I bet it's right underneath the monitor, or something. 
No, it's under the motherboard, one of those awful 3v lithiums.
The next question is - what's that funny header underneath the
motherboard for?  It looks like it's wired as the 8-bit part of an
expansion slot, but it's a bit hard to tell.  I can't even see anywhere
that a cable might come out, if it was something like a modem (which
would make sense).
