i looked at that model too, but i thought the hydrohut looked better built. it has an all steel frame, a 2nd floor which fits very snugly, and it has holes for the intake/exhaust instead of a soft sock setup.
for me, since i was going to spend close to $200 on something, it made more sense to go with the unit that seemed like would last longer and which had the best ability to upgrade as i went along. the hydro hut has 4 vents for intake/exhaust fans, as well as 3 vent flaps near the bottom allowing the ability to set up a passive airflow system.
had i gone with the system HTGSupply sells, i would have had to purchase an additional fan just to create my passive airflow system. instead, with the hydrohut, i purchased a 265 cfm inline fan hooked up to my carbon filter and cooltube reflector for my light
i'm not dissing the other model, i'm just laying out my reasons for purchasing one unit above the other. the great thing about HTGSupply is that they do in fact ship everything stealth. i decided that it was worth it to go through someone else on that purchase, knowing that i was giving up any stealthiness. the other model looks like it probably works just fine. but i'm anal about anything that i put a lot of time into, and want to control every single aspect of it. i don't second guess my decision to buy the hydrohut over that other unit.
