So the cable labeled next to J5 goes to the hole marked LED in the second picture, above the two 5v lines?

I'll let you know as soon as i get the wiring all done. The connectors wires from exxos are so small, so i'll need to join some extra wire onto it. I thought they'd be thicker xD

Hi again. After several hours of connecting wires, soldering and stuff, the PSU is complete and it power up the megafile board.
It also powers up and seems to send activity to the ST 238R too.

Unfortunately i have a huge issue. I've nothing to secure the drive with. And i can't power it on properly f it's touching the motherboard.

I have nothing capable of holding the drive at all.

Anyone have suggestions?

A nice big chunk of anti static packing foam under the drive is the old go to that works for bench testing. Or are you after a permanent solution?
