Building a "wood chasis" for 15" monitor

[SteveJ34]

While toying with design for several bartops, I turn to a stack of 15 inch monitors I plan to run vertically for classics, pacman, ms pac, galaga, etc.

To aid in standardizing the monitor mount and adding sturdiness to the design, I think I would like to decase these and mount to a wood frame chasis, something simple in the shape of:

The ones I have decased and looked at thus far have 4 corner mounts screwed into the corners of the front of the plastic case. The PCBs are just loose fit in plastic slots in the case which of course fit snug, when the entire case is together.

I will need to mount the PCB board which is what the ==== represents in the above ascii diagram.

I was just planning to make a simple right angle chasis out of plywood or mdf, cutting a hole in the front piece with a jigsaw with perhaps a diagonal support on each side.

These are currently just mounted to the front of a plastic case so I didn't see any problem with replacing the "plastic chasis" with a "wood one" in terms of upsetting any existing ground.

I was planning to "be very careful" when actually mounting to avoid any high voltage and so not having to discharge each one.

Is there anything "flawed" in my plan?

Nothing flawed.  To support the corners better, go to the hardware store and look for a set of 4, 3/4" x 3" mending braces.  (3/4" minimum, can go bigger).  Place them tangental to the tube at the corner and run the bolt through one of their holes, and screw the other holes into the wood.  This will provide a LOT of support with no fear of breaking through the wood, even thin 1/2" wood.

However don't set the circuit board directly on the wood.  At the very least, place a piece of plexiglass beween it and the wood.  Ideally, raise it up at least 1/2 an inch using computer pcb riser plastic posts or something similar.  This will help heat disapate better and prevent any shorting with any moisture that may be in the wood/reduce fire hazzard.

Understood on using PCB risers, was planning on this.

Say something more about the mending braces though...

Are you describing using these somewhat as a big "washer" to prevent the bolt from breaking the wood I am planning to mount to or

I look forward to your reply.

Yes.  See this previous thread in this fourm about this very topic, complete with pictures!!

Excellent.

Thanks for the input, Guru.
