I took a cabinet from an xt, and it occurred to me to use a 5-inch green phosphor tube, which are normally used in medical instruments, I disassembled an old 9-inch monochromatic vga monitor, and with your logic I made the 5-inch tube work . then with parts of a mini tv, cut the front and add it to the front of the xt, some paint, new screws and a mother of a 386, they completed the job.
