Cooling options are quite rudimentary. There is a single 80mm intake at the front of the chassis, impaired by an undersized stamped grille and the holes located on the front bezel. Although the included fan is quite loud on its own, the sound was amplified by the smallish stamped grille. I quickly disabled the fan only to minor detriments: the hard drive temperature and overall case temperature raised a couple of degrees Celsius. Finally there is a single exhaust located on the back of the case: a large 120mm. The sound is tolerable, due to the lower pitch of the larger fan. But, ever since I returned my Pentium 4 back to its default speeds, noise level has become the predominant factor. Using the old seven volt trick on the fan made it whisper quiet. Although I could not find actual specifications for each of the fans, by feel, I would guess the 80mm fan pushes around 30CFM while the 120mm pushes around 80CFM at 12V and 50CFM at 7V. Modification possibilities to increase cooling potential are numerous. There is plenty of space where the 80mm is located for a 120mm and aluminum’s easy-to-cut nature makes it easy to add more fans if need be.

The gTower is an incredibly flexible case. I have seen in used in manufacturer demonstrations (you can see two gTowers in the background of this picture, one with a modified window), it would make a great LAN case due to its low weight, and would serve admirably under anyone’s desk. If you are interested in watercooling, gTower is almost the perfect mid-tower for the job (it is the choice case in Cooltechnica’s pre-installed watercooling solution: the AquaXtreme XG). The case is wider than your typical tower, has the perfect spot for Ehiem 1048 sized pumps right behind the removable hard drive cage, and comes with the 120mm exhaust, ideal for mounting small radiators such as a Black Ice Extreme.
