When we remove the left side panel of the Bitfenix Shinobi XL, one thing is immediately noticeable. The side panel is much heavier than you'd expect looking at it. Bitfenix used steel that's thicker than usual, which explains the weight of the case. One panel weights 2.3 kg. It's one way of preventing unwanted vibration and resonance.
The interior looks like you'd expect. Tons of space, and a very large motherboard plate with a big gap to easily mount a CPU cooler backplate. Around the sides there is plenty of room for hiding cables, nicely finished with rubber. Above the motherboard plate there is almost 3 cm of space for hiding away cables. The Shinobi XL makes cable management a piece of cake. Due to the width of 24 cm, there is still enough space for a tall CPU cooler. A cooler of 18 cm should fit without a problem. There is room for long video cards as well, we measured more than 33 cm of space.
To take advantage of all that space you do need to leave the hard drive rack as it comes, at a 90 degree angle. You can turn it 90 degrees, facilitating air movement along the disks, which is a good idea if you plan on using all seven disk slots. You do sacrifice room for longer video cards if you do this, and removing hard drives is a bit trickier.
The hard disks are mounted in trays without any screws, and small silicone rings are meant to absorb vibration. 5.25-inch devices can also be mounted without screws, with a clamp system that feels more solid than we're used to. All-in-all, the interior gives a very solid impression with a nice finish.
