OK, this will sound childish to the hardware guys, but how do I open the SheevaPlug case? It's out of warranty (over 30 days) and I have an external 5v 3a psu on order. The Sheeva has been working well, but runs hotter than I'd like and I'm concerned with longevity. I pulled the 4 plastic feet out to expose the philips-head screws and loosened them. However they don't fall out as I assume they would and the case halves are still tightly joined. Are they glued? Is there a trick to getting them apart? I hate to just start prying with a knife without really knowing what I'm doing. Could someone whose opened a SheevaPlug tell a newbie how to do it?
