Question Trimming Less Off than OMGWTF

[Joshy5]

I have partially trimmed my Wii, but cut way outside the OMGWTF trim lines, as I want extended areas that I can drill mounting holes into, to mount the board.

All the Trim Guide says is "Trying to cut out less means that there are more parts of the Wii motherboard that could throw errors if they’re only half connected"

Now I have removed all components from outside the OMGWTF trim lines. Should that be OK? Or is it prone to other problems?

When I drill mounting holes, I will sand down the holes so no layers are shorting, cover them in solder mask, and cover part of the screws with heatshrink tubing.

Is there a reason you aren't using the mounting points that already exist on the Wii's motherboard? Properly sanding small holes like that is pretty difficult to do

The Wii motherboard sits over the display (6.5") and I didn't want to have to put mounts on the back of the screen. 1. Because I didn't like the idea of the extra weight of the MB and heatsink being mounted to the back of the screen. 2. I want the MB as close as possible to the screen, and there's not really room for mounting points. 3. I'm using the main 4 MB mounting holes to mount the heatsink to the board.
I may be using the existing mounting holes marked in red, but not sure yet, as I may need to trim more off, depending on fitment of other components.

So are you saying I should be good, assuming I prep any newly created holes appropriately?

Can't say for sure whether that trim will work, but it might if you do a really good job of sanding. Is there not a way to mount the Wii to the back of whatever case you're using? That way you don't put any weight on the screen

Unlikely to be able to mount to the back casing, but I may have to make design changes if the Wii trim doesn't work.
Thanks!
