I like the idea - I did a mod to that effect, but I used a small power supply to power 6 drives, I ran out of power connector from my HDD and didn't want to use y-power connectors. With the supply you're using, did you set it up so when you power on it starts. or do you have a separate switch for it ?- I ran 2 pins from the new supply (green and black) to the main supply so when the main powers up the smaller powers on - power down is the same. I like it alot. Well done
