I believe the results of custom lighting are worth voiding a Xbox 360s warranty, which dismantling the casing will do. Though working on the innards of a $300 piece of electrical equipment, this mod doesn't require much soldering skill, however patience to do the job correctly is a must.
I hope you complete this instructable and can light up night after night of gaming!
**** Disclaimer ****
I am not liable for any damages or injuries that occur from following the instructions of this tutorial. Opening a Xbox 360 will void the Microsoft provided warranty, and there are capacitors and other electrical components that can cause electrical shock. Though it is highly unlikely you will be harmed by the innards of your Xbox 360, be aware that the use of a soldering iron and hot glue gun can be harmful to human skin. Use caution, use common sense, and have a fun time completing this mod
Step 1: Parts Listing
Any cheap heat based soldering iron can complete this mod, I used a 15 watt Radioshack iron.
I suggest .022" Silver Rosin Core Solder for easy flow and solid connections. Can be purchased at a local Radioshack.
Dual 4" Cold Cathode Kit
The main colors to choose from are red, green, or blue. CCFLs require an inverter to step up the voltage to light up the tube, going from a 12 volt source to 680 volts into the tubes. Any kit will come with an inverter, tubes, and switch.
Here are some sites for purchasing the tubes. I have used all of these sites whenever I need CCFLs to shop around for prices, my favorite is MountainMods.com linked below. You can purchase R,G,B from most of them, while more unusual colors (UV, Yellow, Pink) may cost more due to lower demand.
MountainMods has been around for awhile, and has excellent prices on CCFLs in every color. I recommend you seek them out first for their price, selection, and service. Here is their CCFL page.

***Note, I'm not sure what has happened in the past year or so, but it's becoming really hard to find Dual CCFL kits that aren't a complete ripoff (i.e. Above $7 for both Dual 4" and 12" kits). If the links on this page die, since retailers update their urls and deactivate items, find your own kits through google. I've bought over 50 CCFL kits, no matter where I buy them from, they are all the exact same tubes and inverters (Some places, like Oznium.com which I do not reccommend, put new boxes on the inverters, which doesn't make a difference), a higher price does not mean higher quality.***
Vinyl electrical tape, the thicker the better. Used to hold wires together and shrink the inverter.
Used to crack the outer acrylic tube on the CCFLs, we will need the fragile glass tubes by themselves to fit inside of the Xbox 360.
Hacksaw / Flathead Screwdriver
The cubes at the end of each CCFL hold the acrylic tube onto the glass tube. Sometimes they can be twisted off with some force, but usually the cube will need to be cut and cracked open with a flathead screwdriver.
Knife or Wire Strippers
We will use the wire that comes with the CCFL kit, it is 20 AWG (gauge) wire, large enough to be easily handled, able to withstand the stresses of being put inside a Xbox 360. Stripping will be for the very tips that will be soldered to the 360 motherboard.
Hot Glue Gun & Glue Sticks
Holds the CCFLs in place, along with any stray wires.
