Cleaning the lters

Dene XL R2 is equipped with two particle lters at air intakes to prevent dust from entering

the case. To ensure optimal cooling, lters should be cleaned on a regular basis.

• To clean the PSU lter, simply slide the lter toward the rear of the case and remove

it; clean any dust gathered on it.

• To clean the front lter, open the front door panel and push the symbols on the hatch

to open the fan door. To completely remove fan lter, pull down the lever on the top of

the lter. Once removed, the lter can then be cleaned directly by hand or with water if

fans have been removed.

Power/HDD LED activity

Dene XL R2 features an LED on the front panel that, when lit, indicates the computer is

receiving power. By changing its connection on the motherboard, the LED can be used to

indicate HDD activity. In either case, connecting the LED to the motherboard is optional;

computer functionality is not dependent on its connection.

Adaptable hard drive cages

Dene XL R2 features two HDD cages - the upper cage may be removed and/or rotated,

and the lower cage may be repositioned.

In its original position, the upper HDD cage has been strategically placed to optimize a clean

build with excellent HDD cooling and cable management. By removing the upper HDD cage,

Dene XL R2 supports graphics cards up to 400mm in length. When the upper HDD cage is

rotated, it acts as a guide for the front fan and directs airow to the graphics card. To remove

or rotate the upper HDD cage, the two thumbscrews securing it must be removed. Following

rotation or removal of the HDD cage, re-insert in desired position and secure the thumb-

screws in new position or remove completely.

The lower HDD cage can be repositioned to provide more space in the front of the case.

This extra space is useful for front-mounted water-cooling radiators. The cage is secured

with seven screws: four under the case, two in front of the case and one on the motherboard

plate. Once the screws are removed, the lower HDD cage can be moved further back in the

chassis to one of two different positions, depending on how much space is required. The

cage is re-secured by screwing the four screws into the base of the case.
