partitions perpendicular to and between the top plate and the bottom plate forming bays between adjacent partitions and between the top plate and the bottom plate, each bay being configured to retain a ruler device;

a handle structure between the top plate and the bottom plate, the handle structure including a handle configured to rotate between a recessed position, in which the handle is recessed between the top plate and the bottom plate, and a use position, in which the handle extends perpendicular to the top plate; and

a nut structure between the top plate and the bottom plate, the nut structure including a fastener aperture configured to engage a fastener of a chassis to secure the ruler device module to the chassis,

wherein the tray includes a plurality of posts for coupling a board to the tray.

2. The ruler device module of claim 1 , wherein the handle structure includes handle airflow apertures configured to permit airflow to pass through the handle structure.

3. The ruler device module of claim 2 , wherein the handle airflow apertures are in the shape of a hexagon.

4. The ruler device module of claim 1 , wherein the nut structure includes nut airflow apertures configured to permit airflow to pass through the nut structure, and wherein the nut airflow apertures are in the shape of a hexagon.

5. The ruler device module of claim 1 , wherein the slot includes an open portion and a slot portion.

6. A computing system comprising:

a chassis including:

two side plates;

a front window and a rear window at opposite ends of the two side plates;

two pins, with each pin extending from a separate one of the two side plates and at the front window; and

a fastener;

a main board housed within the chassis;

a ruler device module including:

a top plate;

a bottom plate parallel to the top plate and extending beyond the top plate in one direction, the bottom plate defining a tray where the bottom plate extends beyond the top plate;

a pair of side plates on opposite sides of, and extending between, the top plate and the bottom plate, each side plate including a slot that is configured to engage with one of the two pins;

partitions perpendicular to and between the top plate and the bottom plate forming bays between adjacent partitions and between the top plate and the bottom plate, each bay being configured to retain a ruler device; and

a handle structure recessed within the top plate, the handle structure including a handle configured to rotate between a recessed position, in which the handle is recessed within the top plate, and a use position, in which the handle extends perpendicular to the top plate, for removing and inserting the ruler device module from the chassis; and

a daughter board coupled to the ruler device on the tray, the daughter board configured to connect the ruler device module to the main board,

wherein the tray includes a plurality of posts upon which the daughter board sits for coupling the daughter board to the tray.

7. The computing system of claim 6 , wherein the handle structure includes airflow apertures configured to permit airflow to pass through the handle structure.

8. The computing system of claim 6 , wherein the ruler device includes a nut structure including a fastener aperture configured to engage the fastener to secure the ruler device module to the chassis, and wherein the nut structure includes airflow apertures configured to permit airflow to pass through the nut structure.

9. The computing system of claim 6 , wherein the fastener is a thumb screw.

10. The computing system of claim 6 , wherein the ruler device module overlaps the main board within the chassis.

11. The computing system of claim 6 , wherein the slot includes an open portion and a slot portion, and the pins sit in the slot portions with the ruler device secured to the chassis.

12. The computing system of claim 11 , wherein the open portion faces the chassis so that the ruler device module can be lowered into the chassis to place the ruler device module into the chassis.

13. The computing system of claim 6 , wherein the handle structure is recessed between the top plate and the bottom plate.

14. The computing system of claim 6 , wherein the ruler device includes a nut structure including a fastener aperture configured to engage the fastener to secure the ruler device module to the chassis, and wherein the nut structure is between the top plate and the bottom plate.

15. The computing system of claim 14 , wherein the nut structure includes a first nut structure at one side of the top plate and the bottom plate, the nut structure including a second nut structure at an opposing side of the top plate and the bottom plate, the first and second nut structures being adjacent to the pair of side plates, and the fastener includes a first fastener and a second fastener.

16. The computing system of claim 6 , wherein the ruler device module fits recessed within the chassis.

17. The computing system of claim 16 , wherein the chassis is 580 mm long.
