The only difference between a 27" tv and arcade monitor is a few kilograms of plastic. 90% of the weight is in the tube.
To mount it, search on here for decasing, thats going to get you a bare tube, which you can mount into a frame off an arcade monitor, or else you will have to add a shel perpendicular to the monitor surround, and put a block on it to stop the tv moving, and then a cargo strap or similar to hold it in there securely against the block.
