Well i'll comment, It sounds like you've got your equipment and it just needs to all go in.
ALl the usual advice i suppose.
Passive intake(s) to the bottom of the unit ,
active exhaust to the top.
I would forget about a Veg and Flower chamber. Just go the Clone and Main chamber. It will allow more room for your plants to expand.
I have a similar wardrobe but your looks a big bigger and deeper, so you'll have alot of room to work with.
Throw up some pics of your gear like filters and fans and lights, so we can get a better idea of what you've got to fit in
Good luck with it.
It's the best project you'll ever do
