No need to remove the cabinet. Open the door and the floor of the cabinet is screwed down and easily removable with a screw driver. Same with the small floor panel that is around the return air grill. Its not much larger than the grill but certainly improves visibility and access if you need to get at the AC unit.
Another common issue with the MS 34T/HT is the cold air supply duct runs vertically up behind that cabinet and can be seen by removing the back panel of the cabinet (also screwed from inside the cab) and/or removing the stereo speaker higher up on the fed side of the duct chase. The problem is the flex duct on many have either not been attached at the top or were one screw that has pulled out of the flex duct.
It is a real challenge to reattach it but can be done.
If anyone finds this issue PM me and I can go through the process I found worked for me.
