Powerful Homemade Burning Laser built-in computer components

Here is a burning laser that I built almost entirely of old computer parts, power to 250 mW. The power, multiple laser diode heat sinks and all came from a computer. I had Aixiz module and LM317 and resistors to pay, but only cost a few dollars. Before disposing of the computer stuff, take a look inside and salvage useful stuff! I drive my 1200mW blue laser with an old computer power supply.
