Hi Antonivs,
Well, now I do realise that ;-) No, I didn't know you had three modular cases, good to hear that, now I understand your reasoning, then it sounds indeed fair enough. Just in case you didn't had that, wanted to warn you. I am glad to hear for you this is rather fun and a puzzle how to come to a compact rack! :-)
Just one thing that wonders me, don't you feel it's pity to use in such small rack the HP space by the rather large 0-coast and 0-ctrl modules? Of course they are very powerful modules that can do a lot, so from that point seen, indeed it might make sense. Either way, I like to wish you good luck with your little-box-puzzle :-) Kind regards, Garfield.
