The AT&T repairperson who replaced my motherboard did what you describe 
(yank, pull, snort!) until the top came loose with a loud Snap! She said
"Customers hate it when it makes that noise." so I think you have the 
procedure right. I think that the case is molded on AFTER the unit is 
assembled, using the frame as a mold.

Mee Too! There isn't a socket on my mother-board for one, so if it exists, its
a card. Has anyone actually Seen on or gotten a firm price for the thing? I'd
love to do slick graphics on the thing if I could!
