Review: Good Quality - Like the one other comment at the time of writing this. "The drive bay cages were super flimsy feeling. This case is also very compact. " I completely agree with his/her statement. The product is in good condition when delivered. So not like the other individual where it was damaged. I have not powered on just yet. Will update this portion then. The space between the fan and back plane is very limited. I have huge hands, which means you will have to unscrew the fan brackets to plug in Molex 4 Pin connecters to the back plane. The fans them self's are clip/slid on which mount to that bracket I spoke of earlier. I did like that, easy to remove and replace. Which brings me to the Molex 4pin for the fans which is at the BOTTOM CORNER in that already confined space !! Will add pics at some point. I am thinking of returning this. Will test it over the next 2 days of this comment and update anyone looking to purchase this product. If it works well no issues with the drives, fans, etc. I might keep it. Looking like a BIG MAYBE. Here is a thought... move the fan bracket to closer to the back plane with minimum gap. redesign the back plane so the Molex connectors stick just past the bracket to make a connection. If you are thinking the fans might get in the way... remove 1. Or use smaller ones. You do not need 3 120mm fans. Summary. 3 stars for inconvenience on how things are located The build quality of the cha it self is good. The drives are Kind of flimsy but fit. The design could use an over all update. Location of the Molex 4 Pin connectors on the backplane... Could easily provide an bracket parallel connections on the backplane it self making it one... Move that Molex 4 pin for the fan to a more convenient location. Not worth $762 including tax that I paid...If it were $450-500 including tax... I would say 100% worth the buy. But considering the price. I expected more/better design work. Update: As I mentioned space between the HDD back plane and those fans is extremely limited. This was a test build to see if it works well. Answer- Yes Fan are kinda loud but work well. Don't think I will hear them when the cha is closed and inside the rack. Like this comment if you found it helpful so others can see.
