Overall decent quality. The plastic drive rails were a little cheap, but they work. I had to modify the peripheral bay in my case and bend the tabs that usually hold the CD drive and other things. Mounting holes on the cage were plentiful and there were no issues adjusting the drive bay and bracket. Once in the subject is strong. I also modified the front air intake and put a dust filter on it. I would recommend also installing hard drives (if mobo is still installed) and a 120mm fan before installing the cage. In general, the purchase is satisfied.
