man i got the 400w from htg with the euro hood you can you should be able to vent out the back because hook up some air duct and just bend it to the back so it vents out the back instead of going straight out of the sides, I vent out the front of my cab so you should be able to the same thing just in reverse.....I also got the 250cm can fan from them to cool my light works great its 39 bucks ready to plug in.....few months you will a few monsters in their ready to burn,and save money in the long run because yo don't have to buy off the street............ shit you might even want to get the 600w digital ballast because its only a few bucks more and alot more light the more the better the bigger the buds.....but I don't know how much hotter it will get then the 400w
