Very quiet and nicely made.
We were hesitated at first from reviews that said the fan in this unit is loud, and were about to go with a much more expensive $200+ unit. But after acquired it and installed and connected to the system and power up, its fan is very quiet. So if you are still not sure and worry about the fan's noise, don't worry anymore, go for this one and you will not be disappointed. One thing to mention, silly us (me helping my teen son), not sure which port to connect the cables to the sata drives and the graphic card, because none of the ports in the back side of the unit were marked. We had to uninstall the unit then inspected each one of those ports and found they are all the same (having the same number of pins in all of them ports). After we were happy, reinstalled the unit and just plugged any cable to any port, they all power up and work fine. The mesh screen matched the haf-x case making it looked very nicely!
