It's my bro's power supply unit which he intend to convert it into a lab power supply in order to power up fans and charge rc car batteries.
(This project was completed along with my fan controller, he was just too lazy to post it up)

So got all the items from Jalan Pasar.
5x 3way binding posts
10ohm 10W resistor
on/off switch
a LED with resistor.
and some heat shrink.

Since photobucket is so f-ed up, will update on pics later.

And reference was from here:

So opened up the PSU and look at what we found inside.

The metal was really really hard. He had a hard time sawing off that little piece.

=( Missed out alot of pics in the process. Was busy doing everything and forgotten about pics.

My bro did all the hard job like drilling and cutting. I helped out with the more delicate parts like acrylic and wirings.

Like mentioned, the metal was very hard, thus hard to drill. Even harder when there'll be 5 holes to be completed.

Cover was sprayed a few layers of black followed by another few layers of clear.

Then it's time for the wiring part. Bundled all wires according to the colors, cut off the negatives which will not be used, add in all other components according to the reference (see first post)

Before putting back everything, we tried to power up the PSU. Fan didn't move, no power. PHAILED!!

Turns out that the binding post was somehow joint to the cover... meaning all 12v, 5v, and 3.3v were connected in a way. So had to take out all binding post, insulate them with tapes, continue the hard work of tying them all back.

Luckily it works this time. And so, work is almost done. (Realised the last binding post is a bit tilted?)

Then there's a hole where initially the wires come out from, it was covered with a small piece of acrylic sprayed black and the switch and led was placed there.
Added some knobs at the bottom to prevent scratches on that surface.

And the corners, they hold really firmly considering there aren't screws to hold them tight. So there you go, a lab power supply...like the one used in school labs, only that this looks cooler with the blue fan and acrylic cover.
