I am building a UAII cab from plans using MDF and am up to the point where I need to build a mount for the monitor. To work out the height I first need to make a bezel, before doing that I need to work out how to mount the glass/plexi I'll be attaching the bezel to. However I am stumped on how to mount the glass/plexi to facilitate removal from the front

If somebody can comment on the ideas I have below, or suggest various ways to mount the glass/plexi I would be most thankful.
1. Velcro - I could attach velcro to the back of the bezel (cardboard at this stage) which is attached to the back of the glass. However, I am assuming that the bezel would come off the back of the glass/plexi (given I want the velcro to be pretty strong) and wouldn't you see the glue through the glass used to attach the bezel to the glass/plexi?
2. Slotted/Pressure - I had thought of designing some sort of clamping system that you could apply pressure on one side forcing the glass up against a frame, however this would mean the glass/plexi would have to be mounted from the rear (meaning the monitor would have to be removed in order to access it - but how many times do you need to remove the glass/plexi for cleaning?)
Also I am planning on fitting a 21" flat screen monitor for my display, however it does leave me with a gap of ~115mm (4.6") either side. I can buy a second hand 68cm TV that will reduce it down to ~80mm (3.2") for ~$100. On viewing many, many cab photos one of my biggest turn offs is the "large bezel housing the small monitor". Does anyone have a cab photo showing one having a similar sizing (115mm gap, or 4.6" gap)?
Cheers.
