All units, on one vertical. Kaiju bottom, C2A with power box second shelf, Beepre third, CD player fourth, Eros and TT on top. 13.5" ish deep with open on all sides, 24" wide.
I'm wondering how much space I should factor in above the Kaiju, BeePre and C2A given the hot weather. I'm planning on 1-1.5" elevation of all units above the bottom of their respective shelves.
