The different versions of the 200 series have different release mechanisms. For my series (II) with the plastic surround to the display, one undoes the two screws under the display and then carefully pull forward exposing two metal clips holding the two halves of the case together at the front. At the rear, remove the screws holding the top extrusion in place in the top corners and possibly at the centre line as well if I remember correctly. Once you have done this, it is easy to remove the top half of the case. Removing the bottom half can be more tricky as you will likely end up removing screws that do not need to be removed and it is then somewhat difficult to reassemble due to the fiddly nature of getting to the screws and nuts etc back in place.

Remove the top half of the case and then spend some time working out how the rest of the unit goes together - it is all very logical and well made once you have worked out which screw does what.

I can't advise re source of RCA sockets I am afraid.
