Yess here's my current grow http://forum.grasscity.com/micro-grows/1296749-kaya-gold-144w-led-stealth-grow.html/page-5#entry19904471
I read the 10th comment and if you want to keep it the same size i suggest add another outtake fan. just my thought i could be wrong but it could work
EDIT: Holy moly I just thread necro'd so hard. Still good info though. My suggestions would be, align your outtake fans with your lights, this vents heat most efficiently; and invest in a better light setup, with at least one light with a colour temperature of 2700k and one with a temperature of 6500k, this simulates the full spectrum available in sunlight for both grow and veg. What are you using for nutrients? This is a very important thing many people make mistakes with. Too much or too little and you'll kill your girls quicker than anything else, except for overwatering.
it doesnt seem that you listed the cost of the cabinet even if it was free for you for everyone else, that could be a big chunk of change if someone has to buy a new one looks good
