That area in front that holds 4 DVD units is open unless you put 4 opticals in there. The bottom portion is hard drives, and that is where a 120mm fan can also be installed. It has a side vent that (and with my wife's mobo fits exact to her cpu fan..direct air from the outside to her cpu). You could also mount an 80mm fan at that spot. Below the cpu side vent is also another open vent (but no holes for fan mounts).
I will be mounting 3 optical drives, 1 floppy, at least 4 hard drives, and I am not worried at all. It is deeper then my huge Antec by about 1 inch. It is not as tall (but to me that was wasted space on the Antc), and slightly more narrow.
My wife is running an Core2 Duo and it is running very cool. I will also be running a C2D.
They have to spend..my guess is $10 to ship the thing, so a $20 case is pretty good. I have spinal problems, so I have to get a lighter case. For this price I can not see how I can go wrong.
After running my current rig with 2 intake, 2 exhaust, 1 side fan (all 80mm), I will never go back to 80mm fans after I saw the air flow of the 120mm fans in the one I built for my wife.
What I will miss is the nice rails of the Antec for optical drive mounting. They just slide right out and then slide another unit in...those rail mounts are real nice. But that is all I will miss. Well...also the Antec is just heavy duty..when I close the side it sounds like a car trunk closing lol. The new case is thin..not as easy to put the side panel on..you have to slide it on..not slam it closed.
What I will NOT miss on the Antec is the 5 80mm fans. The 120mm fans..both the one stock in the unit and also the extra one posted are very quiet.
