New grow box

Ok, I'm thinking bout building a new grow box and i was either gonna do a PC, Cabinet or a homemade on out of some old wooden wine boxes (L 20.5" x W 12.5" x H 7.25")
That i was thinking about stapling together and growing with them... I have quite a few and i was either gonna do two (L 20.5" x W 12.5" x H 14.5") or 4 of them (L 41" x W 12.5" x H 14.5"). Would the 2 crate one work with the limited space? btw the crates will be turned onto side so they will be tall... and i can do anything i want to these ex. drill holes for wires, fans lights etc
