TnS,
I'm about to move into my new apartment and have decided to start grow-op since I don't know anybody out here. I wanted to be as stealthy as possible (a little first timer paranoia), so I've been lookin over the internet for a month to find cheap, homemade, SECURE, stealth growing cabinets. (secure, meaning i can lock it in case management comes in, etc.) So, after I read your post, I went to Lowes and got some stats on the cabinet.
I found a few at the store that have greater depth in them than the one you posted and more room for lighting if you use multiple, single fluorescent, closet light bulb fixtures. Lowe's specially carries 18watt bulbs (which produces 950 lumens per bulb) and 15 watts (which produces 510 lumens). (The lumen count might not be the best , but it will better keep the electric company from monitoring your meter.)
I think this may work because the cabinet can be easily painted a bright white on the inside. It is also made of a material that can be easily cut for inserting ducts, fans, and other necessities. Second, with the directions they provided, it would be easy to assemble. The best part for me (that calms my nerves) is end the end, is that I can put a nice clasp and lock on it and it would look just like an extra storage closet!
I hope some of the more expirenced growers take a look at the links below and check the measurments of the closets, paying particular attention to the width and depth for short plants that like to branch out like the lowryder strains and height and width for those that like to stretch tall and wide. Let me know if this is even possible. I'm actually thinkin about givin it a try.

Also, (being about stealth) I've found something on another forum that's homemade and sworn-by to get rid of the growing smell. You may already know about it, but I'm just tryin to spread the wealth:
