[[Image:Mx13-case-empty.jpeg|thumb|right|200px|MX13 keyboard v1 case rendered in aluminum and steel.]]

The case is comprised of 6 layers with a total height of 13.5 mm and an internal cavity height of 10.5 mm.
The [http://deskthority.net/resources/file/11335 design file is here].
The layout supports 76 keys, with the following characteristics:
* ANSI Enter key
* 7-unit space bar
* 1.5-unit Control and Alt keys
* 1-unit Super and Menu keys
* Center-stemmed caps lock key
* '''No FN1-FN12 keys'''
** FN keys are accessed by pressing FN+1 through FN+=
* Key cap profile considerations:
** Escape and Num-lock in row 1
** Pause/Break and Scroll-lock in row 2
** Print-screen in row 3

The TrackPoint stick is mounted on top of the switch plate.
This gives it the right height when used with SA-profile key caps produced by Signature Plastics.
If lower-profile caps are to be used, the TrackPoint will likely be too high.
To adjust the height, it may be possible to mount the TrackPoint stick below the switch plate and further recessed as necessary via washers.
This would require adding a center hole to the plate between the G, H, and B key switches for the stick to pass through.

====Version 2====
[[Image:MX13.v2.png|thumb|right|250px|[http://deskthority.net/resources/file/11258 MX13 keyboard and case design v2].]]
A second iteration on the case design was made to address issues with the first version.
The [http://deskthority.net/resources/file/11258 design file for version 2 is here].
'''Note: This design has not been built and may contain errors.'''
The following changes have been made from v1:

# Revised TrackPoint button bridge to fix design error and reduce impediments to button travel
# Removed 3rd (middle) stabilizer cut-out under space bar
# Moved stabilizer clip holes up 0.5mm to alleviate stabilizer slider friction
# Deleted unnecessary center TrackPoint support holes
# Moved top-right screw hole closer to USB port to better align layers near the USB opening
# Broke up loop around USB port to remove obstruction to wires when closing the case
# Gap for changing ornament color without having to open entire case (just loosen right-side screws)
# Moved TrackPoint buttons down 5 mm away from space bar for better comfort and widened bottom keyboard edge accordingly
# Moved display opening down 3 mm to make more room for it internally and better center it with new, wider bottom keyboard edge
# Recessed USB port 2 mm from keyboard edge
# Removed spring-swap holes for keys G, H, B, V, and N because those switches need to be dremeled to the point where they can not endure spring swaps
# Removed unnecessary button assembly lip cut into bottom layer
# Improved hole fitting for Tappex brass inserts
#* Widened holes in bottom layer for 2 mm inserts from 3.5 to 3,7 mm
#* Widened holes in bottom layer for 2.5 mm inserts from 4.3 to 4.5 mm
#* Shrunk holes for 2.5 mm inserts on last non-bottom layer from 4.8 to 4.5 mm
# Added controller reset button hole below space bar
# Added an extra 5 mm breathing room under SpaceSaver II controller board
# Raised screw hole to the right of the space bar by 3.5 mm to allow greater clearance for stabilizer bar.
