@MgARBITER - I can tell you what I got but since I bought all my supplies local there may be changes in the pricing. Another difficult thing is different lights have different voltages so the resistors you need for green lights may differ from ones you need for red lights. In this mod I got a 12" x 24" peice of plexiglass (cut down of course) from Home Depot for about $7 USD. I got the "frosting spray" from Micheals for about $8 USD. A Dremel will vary in price depending on the model and tips you get. This mod has 20 green lights (14 for the side of the 360 and 6 in the HDD) at Radio Shack for about $15 USD. I also got my resitors from there for $1 USD for a five pack. For this mod I bought 2 packs of 100ohm 1/8th watt resistors, a pack of 220ohm 1/4 watt, and a pack of 330 1/2 watt resistors. Now I recommend better wire than I used but appearently speaker wire works.
