This project is dedicated to Greg the delivery driver. I hope this helps you out brother!
You would be amazed at how many people get an xbox and want to start modding but just don't know how to open it. This tutorial is going to be the most simple tutorial in my arsenal.
First you want to make sure you have the right tools.
-1) Torx 20
-2) Torx 10
If they have a magnetic head, awesome. If not, you may want to consider having a driver on hand that does have a magnetic head or something like THIS (I have a small phillips with a magnetic head that I use)
Next we want to take our xbox and turn it over...
Use an x-acto knife, Swiss army knife, butter knife, or your fingernail... and pry up the "feet" just enough to expose the screws. Repeat on all 4 corners.
The center screws would normally be hidden by the FCC sticker and the bar code sticker but as you can see this box has been open before. It's easy to find the screws. Use your finger and feel where the screws are. Then all you have to do is push the Torx 20 through the sticker and back out. (please don't try to remove the sticker completely unless you know what you're doing. It can make a nasty sticky mess that will attract hair, dust and dirt for eternity)
Now that you have all 6 Torx 20 screws backed out, set them aside. Flip your xbox back over and carefully "pop" the lid up, slide off and set aside.
You're done with the Torx 20 for now. Right in the center, under the IDE cable, there is a single Torx 10 screw that holds both of the "caddy's" together. You can get to it now, but it's good practice to remove the power molex and IDE cable from the hard drive first. Next you want to unclip the power cable from the lower right corner of the hard drive caddy. Remove the Torx 10 and lift out the caddy, hard drive and all. Set aside.
NOW we move to the DVD drive. There are 2 Torx 10 screws that hold it to the chassis of the xbox. They're located on the outer right and outer left of the front of the drive. The one on the right is easy to see and easy to get to. Remove and set aside. The one on the left is recessed down in a nice little "cubby". Use your Torx 10 to back out and use your magnet tip to grab the screw. Make sure not to drop it into the case because it could (however highly unlikely) knock loose vital components or short out points on the mother board.
Next we have to remove the IDE and 12 pin, yellow, power/signal cables from the back od the DVD drive and lift it out.
There you have it. Now you have access to the motherboard, power supply, controller ports, faceplate etc... Please stay tuned for my up and coming "How to remove an xbox faceplate" and other useful tutorials!
Thank you so much and happy modding!
