Building a cab. Hurricane fan question.

I'm gonna start production on my grow cab today. I'll be framing with 2x4's and making the walls out of oak boards. Gonna stain it and was thinking about making a false front, and putting my in it as a display, and have a grow in the back. I'll be posting pics in this thread later today. but my question is, has anyone tried the hurricane inline fan? I am only going to get a 4 incher, as I will have 12 cf of air space.

I also just had a thread a few weeks ago asking about a few different brand name fans and ended up coming to the conclusion on getting the ventech 4 inch fan/carbon filter combo ($100 with free discreet shipping) after someone recommended them to me on the thread i posted. I also got a few other recommendations from some other sources. I saw a bad ass video on youtube where ago used these ventech fan/filter combos in small grow boxes he built because the flange on the filter fits perfectly on the fan with no ducting between. It is also has a one year warranty and the ebay store that sells it will process the warranty for you to make it easier without having to deal straight with the manufacturer. here's the link:

I just made a small box out of 2X2's and 1/2" plywood that is 2.5FT(L)X1.8FT(W)X3.5FT(H) to fit in an extra spot in my room right by the A/C vent into the room. It is on 2" wheels so the intake holes are on the bottom pulling in cool air. I also just found this small cool tube on ebay that is only 12" long for small grows that fits 250 watt bulbs or lower and some of those small 400 watt bulbs. I won it on ebay for $15.50 with $10 shipping so only $25.50. I don't know how big your building your box or if your even what your set up will be as far as lights but just thought I would share it since it was a good deal and there isn't too many small cool tubes. but here's the link for it:

Yea i ended up getting the ventech because the direct filter connection you mentioned.
