The guides available on there are extremely thorough and (at least in the past – I’ve modded dozens over the years, but not in the past 2-3) had information for all models.
Tools you’ll need are either an official kit (will cause less damage) or your usual screwdriver collection and the lid of a CD spindle. Personally I do all the case opening/cracking with a fine tipped wiring tool (like a screwdriver but with a sharp tip)
this might help you ther are various methods to mod a xbox 360
