Dismantling original Xbox (getting the case off)
What you need to dismantle your broken Xbox
Torx 20 and Torx 10 (get these, don’t just try with a screwdriver or allen key)
Some form of a knife, to remove stickers
Wax paper, to keep stickers “sticky”
Step one: Removing the stickers on the bottom of the xbox
Two options, either poke through the stickers, or carefully peel them off. There are six stickers on the xbox to remove, one in each corner, and one under two of the stickers (the bar code one, and the “Xbox Video Game System” sticker
The four stickers in each corner can be peeled back with hands/a knife (or a flat headed screw driver)
Step two: Getting the case off an Xbox console
You can now turn the xbox console over and you should be able to get the cover off from the bottom of the console

It is a mediocre description at best… i never had to take off any stickers, and i ran into problem after problem trying to figure out what to do next. this being my first time trying to dismantle a game console, my only input would be to go a little further with the description… and possibly a little more detail.
Read something interesting about the 360 on Gizmodo, this guy claims when he read Microsoft support his 360 serial number, they could tell he’d opened the console.
“Sort of off topic but by reading him the Y: numbers he knew that my console had been opened. I cracked it open after I got it because there was something loose inside it rattleing.”
I have the easy version of of unassembling xbox not 360 version… under each foot remove the rubber pad there is a torx bit that needs to be removed, 4 feet, 4 total screws, under 2 stickers of bottom, there are 1 screw each, feel for the screw under the sticker and slice with a razor blade to access torx screw, 6 total screws on bottom of xbox in total thats it! pull up top of body which will split away from base, also, a flashing yellow light is an indication of an overheating unit most likely a fan isnt spinning, if your xbox sat and now you try itr and it flashes yellow after small amount of use, id say its the fan stopped up, make sure its spinning when you turn on unit. Good luck!
