Pros: - Not many other options to use 3 optical bays and fit 5 hard drives in it - Works as advertised Cons: - Not enough screws for proper assembly. Bargain if you already have a supply of screws - retractable hard drive brackets are cheap, don't stay on the drive. but they get the job done - very small disk spacing but they seem to work just as cool as any other drive bay. Idle - Most drives in this system are idle most of the time. Heat could be an issue if I'm constantly reading/writing large files from these drives. All in all a super basic adapter. Don't expect to fit more than 5 x 3.5" drives in 3 x 5.25" bays and you will be satisfied. I didn't use the black metal grille front - I saw no point in using it other than to further restrict airflow through this drive basket. I am happy with the purchase. Will be buying again for other open 3x optical bays in this large case I have.
