i should have taken better notes and/or posted this sooner after it was completed, as i don't have all the dimensions recorded.
i THINK this was 42" wide, 36" deep and about 40" tall...not real sure on the height
anyway, everyone's system should be built according to their needs.
i just purchased a freezer and it will only hold two carboys (but it will store lots of other stuff.) the cabinet is definitely a better way to go...cheaper, too, if you do it right.
