Busting things off!
No... EVERYTHING unscrews. Look under the case. 2 SQUARE HOLES. Two screws hold the main power wires. Undo those as well, and 110/240v wires from top and remove in a calm easy fashion! Seriously you wont break anything. The more you undo the better it gets. And the easier it becomes. Unplug and dissasemble everything.
Notes.
Before adding you new DC wires with ring terminals to the main output, fit them to the board. Leave over long. I used silicone, cables from ebay, in SWG 10. Because those two access holes are absent on the new case. I had to take apart again!
I soldered the front connectors, only because, no ring terminals!
Add the new board mount standoffs just by looking inside the old case before you throw it away. Theres one unused, and one that needs two brass ones screwed together. The rest is meccanno!
You may need to fit 2 slim pot washers, when fitting the display or it will not line up properly. Other than that its a first time, 2 hour job. Inc fitting the anderson. The anderson has 4 wires. Supply from board, and the feed to the front 4mm connectors.
