All in one PC rebuild

 HP All-in-one had broken screen, but this salvaged LCD Works.  It was a touch screen, but now it will just be a plain non-touch panel. Making it fit is going to be the main challenge. The system is functional, but the platter hard drive was replaced with a 1Tb SSD.

Testing a salvaged LCD Panel,
Miraculously compatible cables!

Do not accidently mount the screen upside-down.

3D Printed structural non-solid

The LCD will be mounted to a wood back panel, that fits inside the computer where the old touch screen was seated. It just needs some spacers for the cables. For this, some non-solid spacers were 3d printed and fixed on the back, then mounted on the wood panel. This just might work.

Spacers ready to mount
Project in progress...

Inside view: small hole cut for video power access.
SSD dropped into place. Such a tiny motherboard.

Next Steps:

1. mount screen
2. measure and design side brackets
3. drill case edges to line up with the screen mounts\
4. work the cables into place and plug in.
5. screw mount screen and figure out final trim for screen.

Once the spacers are mounted to the panel and ready to install, a few more 3d printed brackets will be required. The LCD has screw holes on the sides which can be used to mount into the plastic edges of the case, where new mounting holes can be drilled. The 3d printed brackets will go along the sides of the screen with screws to enable removal and maintenance.

There are holes to allow the video and power cabling to go through, but the next challenge will be to wrangle the stiff video cable in a way that will not kink or obstruct the components.

When everything is mounted and plugged in, there is a bezel from the salvage LCD that may be able to be used to give it a cleaner look instead of bare metal around the edges. it may not work without modification, due to the (pending, 3d printed) mounting brackets.

cables connected ok, and LCD dropped into place.
from here we can see the webcam being obstructed.

all in one with extra large screen

the bezel still fits nicely.

An unforeseen issue is the popup webcam on the top. it cannot see over the larger screen. The cam can be detached and remounted on the new screen.

1. installing windows
2. updates and drivers
3. attempt webcam modifications
4. prepare screw fixture plan and secure the new screen assembly.
