Things you need to get before you start.....
Very small flat head screwdriver
T12 Torx bit
Blade of some sort (optional)
Can of gas (optional)
Thick piece card or the top of a CD spindle (optional)
Step 1:
Remove the faceplate buy pulling from one end and releasing the clips as you go down.

Step 2:
Now you have to remove the top and bottom pieces that hold the case together. For the top, start out by pushing your small flathead screwdriver into the hole on both sides and unhooking both latches.

Once you have both hooks unlatched you have stick your screwdriver into each of the holes marked by a red dot on the picture below. The green dots are the holes that are filled in. One of the holes is hidden behind a rubber foot. Just remove it and place it somewhere safe forlater. Do this for both sides and the top should just come off. When you have the top, do the same for the bottom one. For the bottom all of the holes are visable.


Step 3:
With both the grey bits removed you can start to work on removing the botton piece of the actual case. On the front there are 4 clips that you have to lift up. This is also where your warranty gets voided! Ive heard success story's from people using gas and a blade to remove this sticker intact but I haven't tried this myself.
Once the clips are off lift the bottom of the case up about an inch to make it easier to work on the back.

Step 4:
For the back you have 2 options.
1. You can make an opening tool to help you release the clips without scuffing the case.... or
2. Use the small flathead screwdriver to do it.
[1] Cut out the top to a CD spindle or a piece of thick card (a business card might even do) and line it up with the holes on the back of the case. Now mark out where these holes are onto the plastic and then cut around them to leave tabs sticking out where the holes are.

Now all you have to do is push your new tool into the holes to release the clips. Each one will click when its done. Repeat on the other side. There is also a clip in the middle that you have to do.

Just push on the case where I have.
[2] If you can't be bothered to do [1] like me then all you have to do is get your small flathead screwdriver and push it into all of the holes until there all unlatched. Do the middle catch the same way as [1] Doing it this way is quicker but you might scuff the back of your case doing it.


Once the bottoms off your left with this.

Step 5:
Now its time to get out your torx bit. Unscrew the 6 long screws marked in red, flip the 360 over and then remove the top.

Once thats off you will be greeted with the 360's internals.

Well thats it folks. I hope this helps somebody out and if you have any questions just leave a reply. If I have missed anything out or something is wrong please let me know so I can change it.
