Like the slide cover as well as the added security for video cards. Also really like the design as well as the arrmor-esque design on the side. Gives the case a sleak look.
The best feature of the Enermax SpineRex Chassis is the spacious interior. I've often found many tower cases have poorly designed interiors and are difficult to work on. The Enermax SpineRex is very well laid out and has 12 plus inches of room for EATX motherboards and long video cards but doesn't cramp the drive bays. Very well designed.
This case has a lot to like. Cooling potential is my favorite feature, fan placement is excellent. I also like the black interior and the roomy modular design.
I'm a HUGE fan of the cable management features. This is my biggest problem when building, so it would be wonderful to have a case that made it easy for me.
