Custom Wall Mounted PC Build


I wanted a PC that could handle multiple tasks from video editing, photo editing, 3D/2D CAD, microcontroller programing and could also output decent audio to my headphones and home audio system.

I tried to re-use as many parts from my old PC to keep the costs down.

I have limited space in my home office so the case had to be wall mounted with easy access from my desk.to USB ports, memory card slots and dick drives.

 My old PC was built into a midi tower case under my desk and was a real pain to access ports and slots.




PC Control Panel

A 3D printed panel is bolted to the lower 2020 alluminium extrusion.

There is an illuminated Power Button, an LED Mode button and Reset Button & also a Hard Drive activity light.


POWER - switches the PC ON/Off and wakes from sleep mode.

LED MODE - Pressing and holding for at least 3 seconds to sync up with your ARGB software and allow the fans LEDs to be controlled by the system software.

RESET- Resets the PC





Working from home during Covid my work setup uses 3 monitors to display multiple test and control systems.

I found the best combination of monitors for my job was a 32" 4K monitor main central monitor in landcape mode and 2x 1920x1200 monitors positioned either side of the main monitor in portrait mode.

My new PC uses the same setup plus a 4th monitor for general utilities.

My work and home laptops connect via a docking station on my desk to the 3 main monitors and can be used simultaniously with my main PC via USB switches and by switching the monitor inputs from the onscreen controls.

The 4th monitor is set into the PC case with the display taken direct from the Intel Core I5 processor




My desk is fixed to a wall at one end of my office and has a pull out section for my mouse, trackball and keyboard.

When pulled out and locked in position the pull out section is alligned with the arm rests on my chair so I can use my mouse, trackball and keyboard and keep my arms supported.

My chair swivels but has no castors ( I removed them to stop the chair moving on my wooden floor) so to get away from my desk I just slide away the pull out section and swivel my chair to the right and walk away.

My new PC is mounted on the wall to my right at the same leval as my monitors and can be easily accessed directly from my chair.








My case is based around an Open PC Frame

The frame provides the structure for the PC components and case to hang on.



Rear view with PSU and PCI card supports




The Open Frame PC comes in a kit of parts and can be easily modified using standard 2020 extrutions parts.


Motherboard mounted on the frame


PC frame with extra 20/20 extrutions added for component and wall mount brackets.








Wall Mounting 

Timber Wall mounting brackets in place. The lower wooden bracket is suppported by a pair of metal shelf brackets.

The top of the PC frame is fixed to the wooden support battern by corner brackets.

The  wooden batterns and shelf are be painted black to match the frame.

I have also added some 2020 bracing at the front rear of the frame to hold the vertical 2020 extrution upright.






Wooden Enclosure

The wooden enclosure keeps the dust out and fan noise in.

It is made of simple 27mm x 27mm screwed and glued timber battens.

The enclosure sits on the top 2020 frame extrusions and is held to the 2020 frame by 2 bolts






A wooden case support bar is fitted across the top of the frame to support the rear wooden joints. This bar just rests on the top 2020 alluminium extrution




Enclosure with Perspex Doors Fitted

The Perspex is ordered custom cut with polished edges from the supplyer.

I have used 5mm Perspex as it is self supporting off self closing hidges.

The door on the right has a cutout for the twin cooling fans.



Door Knob

The door knobs are mounted direct to the Perspex with a metal washer on the screw side and a printed plastic washer on the knob side.



Hinge Mounting

Front of hinge showing front bolt washers and front hinge washer


Hinge Washers Front & Rear

The rear mounting surface of the hinges has a raised area that will damage the Perspex sheet even with a flat washer over it.

I have added a cutout to the rear washer to accommodate the raised area.


Make sure the rear hinge washers with the cutout are fitted on the rear of the hinge as shown.



Hinge opened to show rear bolt washer and hinge between front and back washers.

Picture from my 3D Printer enclose -there is no dust seal on PC enclosre.


The Perspex door are mounted on 3 pairs of Self Closing Cabinet Door Hinges

3D Printed washers and spacers to protect the Perspex click to download 3D Printer files


Front Hinge Support



Rear Hinge Support with cutout



17mm washer for door knobs



10mm washer for hinge bolts





In order to install/remove the case the Perspex mount & fans on the side of the case need to be released and moved to the front of the PC.

This gives enough clearance for the case to be simply slid on/off.







Auxillary Display

The PC has 4 monitors. The 4th is fitted inside the case driven by the Intel Core i5 10600 built in graphics chip.

The monitor is connected to the HDMI out built into the motherboard.

Note this has to be enabled in the bios.

The display is a very cheap £42.00 display from Amazon and has a 7 inch screen with 1024x600 resolution.

This is my utility display and includes a Horloger Windows desktop clock

Argus System Monitor to keep an eye on my fans, CPU memory etc.

I also have a Calendar and local weather gadget gadget.

The display is fully functional and although small can be used for any windows functions.

The display is mounted to the top front 2020 channel by 3D printed brackets


Then click "Intergrated Graphics Configuratio"



Click on "IGD Multi-Monitor" and enable it



BIOS Setting General

Enable Smart Fan Control for System fans (Pump Fan)

Goto "Hardware Monitor"

Select "PUMP1" and ensure "PWM" and "Smart Fan Mode"are selected. Note this should be set already for the CPU 1.


To use the M.2 storage I had to use RAID mode.




I enabled the following

iBasso D2 Boa Headphone Amplifier

Hi-fidelity portable headphone Amp. Wolfson WM8740 DAC Chip + TI PCM2706 - USB signal input, provides I2S interface for decoding.

iBasso D2 Boa portable headphone amplifier, capable of taking the signal from a headphone socket or a line-level output and boosting it to suit the demands of even the most high-impedance stereo ‘phones.

Secondly, it doubles as an outboard DAC and amplifier for PC and notebook use, using USB to stream the digital signal to Wolfson WM8740 and Texas Instruments PCM2706 DACs for processing and analogue conversion.

You’ll find the Wolfson chip inside high-end CD players from the likes of Kenwood, Onkyo, Rega and Cambridge Audio, so it’s fair to say that you can expect a better sound than you might get from the your average integrated audio chipset.

PC setup is simple just connect the D2 up via USB and Windows recognises it as a USB DAC and installs the necessary drivers automatically, with the D2 taking over from any integrated audio solution or soundcard.

3D Printed Parts


PC Motherboard/Spec label

This label is attached to the lower plate of the PC and gives the Motherboard and Processor Type.

Designed in FreeCAD the Text is printed on a 200x20x4mm cube.

I have used a Font called AQUIRE as it was similar to the font used by MSI on the motherboard.

AQUIRE can be downloaded free from BE fonts.


The FreeCAD file can be downloaded below so you can make your own label.

I used the FreeCAD Draft ShapeString tutorial to make the label.




I sliced in CURA using a "pause at layer" script so I could print the backgrount plate in black and the text in white.

The script detail I used are below.

My original CURA file is below


Motherboard Label fixed to 3D Printed Trays


Fan Dust Filter Holder


4 of these are required all different. Just use CURA to flip/mirror as required


The 120mm fans are bolted to the rear of the mounts and fixed to the Perspex fan mount of the PC case


Neodymium Magnets are glued into the recesses on the mounts



A magnetic fan dust filter is fixed to the mounts to keep dust and fingers out.







Finally 2x slide out clips are printed to hold the fan filter top & bottom.

The clip is self tapping screwed to the top & bottom fan filter mounts.



Slide out clips in place




Fan filter and mounts in place behind cutout in the side Perspex door.






USB & Headphone Amp Panel


Panel with USB sockets and Headphone amp installed

Labels for the USB/Headphone Panel

The labels are printed using the Pause at Layer feature on CURA.

This allows me to print the background black and the letters white.

In CURA the labels are "Sliced" then previewed.

The layer where the black base is completed becomes the Pause layer.


The 3D printer will pause at the set layer with the extruder heated so you can pull the black filament out and replace it with white.

Clicking the control button will make the printer restart where it left off.

Memory Card Reader Holder

Using 2 bolts and channel nuts the memory card reader is clamped the the top side 2020 extrution section
