Rails For 5.25" Drives
Antec has decided to go with rails for DVD or CD drive installation. The rails are screwed directly onto the drives and then inserted in one of the empty drive bays. The solution is an elegant one - unless you want to install a 2" deep fan speed controller without any additional perforations. In that case, the controller droops down, marring the appearance of your front panel.
5.25" drives like DVDs or burners are attached to the case using rails.
Small displays - like our test one here - don’t get much support from these drive rails.
