That Lack rack does indeed look great...
if it wasn't as (way to) deep as it is...
Currently I'm thinking of building me a rack from the base- en top-plate of 2 Corras units.
The Corras has the ideal dimensions imho. (not too deep)
I thought it might be possible to stick some spacers (wood?) in between the boards, on the corners.
