One warning: the Syinsi tiles use the "original" format, and Intellijel's tiles are based on a slightly different spacing. They WILL NOT work in an Intellijel-spaced tile row...and vice versa.

well...tbh, if you just screw in the top screws of an Intellijel module...it fits fine and the cover will rest on the lower rail. my 2 Intellijel modules are rock-solid and don't wiggle at all. it's literally 2mm or so. I saw someone lock down a steppy like that in the same case - figured I would try and had a good return policy from the guy I picked up the 1u's from. Also, the intellijels are powered by the usual power connections and not that weird 3 strand one like the Pulp/Syinsi ones. So I like them moreso at the moment - but I really like the idea of a 1u/ 6hp LFO and VCO...and if it comes back in stock, the 1u midi interface.
