I have a fairly cheap tv cabinet / AV rack that I assume is made with particle board. It is sectioned of into spaces for stereo / AV equipment. In one of the spaces I have a very large power amplifier that is nearly too large to even fit. It runs very hot right now and does not get adequate ventilation.
What I want to do is cut two large square holes in the top, leaving room for the other small devices to still be supported and sit up there, a very large hole in the left side of the unit, and either cut a large hole in the right side divider piece, or just remove this divider entirely if it doesn't compromise the structural integrity.
How would I go about make good clean cut that don't look tacky? Is the right divider needed for support?
