My Ultimate iBook SE, An Indigo 466SE with every add-on on you could think of !
This is a Rare iBook Indigo 466SE, Rare because it was only available to edu markets- I got the iBook from an eBay seller (locally - Score!), it was obviously a teachers model, of the hundred he had , most were 366s. Only a few were 466 models, this was the better of the 3 i had to pick from. The project started after I ordered 50 UltraBright blue LEDs for another project, and ended up with a bunch left over.

LED Mod:
14x Ultra Brite Blue LEDS
20-22Ga Wire (I used old phone cord)
SPST Switch(I used a DPDT)
The idea I used is pretty simple, I didn't want to hurt the battery life with the LEDs, so they ONLY function while its connected to the power adaptor. The Wiring is as Follows
7 LEDs in series installed in Display housing.
7 LEDs in series installed in lower case.
Positive lead from DC-IN jack to switch
Lead from switch to Fuse
Fuse Connects to both Chains of 7 LEDs
Both chains of LEDs Terminate at the Negative side of the DC-IN jack.
Voila!, Re-assmble and You're LIT!
Next up, I tackled connectivity.
Internal Bluetooth Mod:
USB BT module(i used the Microsoft Module that came w/my mouse)
20-22Ga Wire (I used old phone cord and a USB-b cable)
SPST Switch(I used a DPDT)
2x W117SIP-6 Magnecraft 5v Relays.
1x 47Ohm 1/8W 5% Resistor
I still wanted use of the USB port so direct wiring of the Port was Out ... or was it . The Wiring is as Follows
4 wires from bottom of USB port
Power +5v from usb jack to switch
Data+ to Relay
Data- to Relay
GND to USB Cable
Next, 
+5v from switch to USB cable
+5v to Positive side of relay coils
Data- relay to USB cable
Data+ relay to USB cable
Finally-
Neg- side of relay coils to Resistor
resistor to board ground
Now-
With The relay pack installed and wired,
the Bluetooth and the LEDs Light when the switch is ON.
When the Switch is OFF the USB port is free to be used, and the LEDS are off .
Voila! Reassemble and you have Bluetooth at the flip of a switch !
Finally .. Cosmetics time!
Cosmetic Mods :
Clear Display Bezel (iBook tangerine)
Clear Palmrest (iBook Tangerine)
Original Drive Door (modified)
The Drive Door-
Pretty simple, just cut,the center section gets tossed, then install (i used hotglue).
The Only other prep was the swap of the Button on the palmrest, and tossing all the shields during earlier stages.
