i would like to recomment dvd player cases to everyone. why ?
-1 unit 19" format usualy
-easy removable front so that custom made front can be attached
-separate symmetric powerboard inside, suitable for most projects (+12-12+5 V )
-easy to find (plenty in the garbage)
for the rest : i know what you mean, i have here several shelves with weird looking cases (that i probably never use)
and boxes full of resqued pots, switches etc.. my favourites are (dont know the english name)
things that are screwed on top of a mustard/mayonaise etc. tube to close it, because i like the colours and forms..
totaly unhandy tough as they dont fit on pots or anything else but mustard tubes..
