Having popped the top off, we get a look at the entire interior. Look at all this modular hardware!

The large interconnect cable even has friendly labeled ends: the side labeled IO connects to the Input/Output board, while the side labeled MB connects to Manitoba, Canada. Or maybe the motherboard...

The I/O board also hosts the power jack, a common point of failure. It looks like fixing a broken power jack will be as easy as replacing this little board. A+
