Test the LEDs, and seal it all up with electrical tape
Reinstall lightbars and brakets, reinstall the front cover, and reconnect the wires.
See more about these fun little LEDs here. The case front has 4 LEDs in it, so each side has a top and a bottom LED, making some interesting colors in the middle. Even more interesting, the little airbubbles in the plastic lightbars glow two colors: one for the top, and one for the bottom.
And, they pack everything in baggies, and LCDs are put into ESD bags, and shipped in boxes so things don’t get dropped, crushed, smushed, etc. And yes, I’ve bought from them again and again, and I highly recommend them for LCD stuff.
Here’s my “partially-assembled-and-disassembled-for-the-photo” breadboard power supply. It comes as a kit from SparkFun Electronics, as seen here, along with the optional heatsink for the voltage regulator, as seen here.
