How to open 5155?

[Jim Leonard]

I must be a dolt, but I can't seem to figure out how to open up my IBM 
5155 Portable.  How do I crack this thing open without damaging 
something?  I want to add some cards to it (including a hard drive which 
is going to be tricky since it doesn't look like there's a lot of room 
in there)
