So this is a new case, bought strictly for the amount of hard disk drive bay sleds. However I love the fan hub that allows me to control all of the fans through the switch on the front of the PC. Which is covered by a ventilated swinging door, two massive 140 mm fans strictly for just a hard drives, plus two on the top and one back and another on the side all intake 120 mm fans passing the air through the system and out the front. This system now has its PCI expansion card for SATA drives allowing me to add another 10 drives if I wish. We also added the five and a quarter floppy drive bays at the top of the build in order to install the 2.5/3.5 (one of each at a time) drive hot swappable drive docks station. Then we did all of the cable management and finished it up! Tell us what you think!
