I own an 8000T and haven't even been able to successfully remove the top cover (out of curiosity - it works and sounds fine). It seems like there must be a trick to it, unless I'm completely clueless, since it won't let go of the top with all the screws removed. I can move it just so far, then it resists enough to make me think that I'll break something if I push or tug or flex it any more. I feel that the front panel extrusion is retaining it in a death grip, with no obvious means to make it let go. Oh well. Any smart (or dumb, if I'm deserving) tips here would be apreciated.
