Well if you got a buddy with a router, workbench and all the stuff, yeah. Just the little extras Ap does is nice. Like the hole for the dowel to line up/lock cages together, the t-stat probe channel on the bottom for heat tape so the cages can sit flush on each other, the routed and fitted LEDs with routed cord channel out the top so cages again sit flush on each other and the whole shelf deal. its all done very nice. Just got to order them BEFORE you need them lol.
