If you are going to perform the case mod, then you need to listen up.
Please go here and print it out all the pictures:

Theres 5 pages to print out.
When you come to the part where you are installing the fan cover, please stop and follow these instructions:

Its very easy and simple.
MAKE SURE THAT THE SCREWS ARE ONLY TIGHTENED AS MUCH AS YOUR FINGERS CAN TIGHTEN THEM!. Do not put so much force into screwing the screws down. Dont use the power in your wrists. You will only wear/strip the screw and you will regret it!
By printing out the pictures, you will then be able to keep track of every single screw you unscrew.
After you unscrew, place/tape the screw down onto the paper. This is the best method of keeping track of the screws.
Helpful hint:
If you dont wish to touch the motherboard, the dvd drive, and the other components, then the easiest method would be to just install half the case. By doing this, you are basically just unscrewing the case, removing the old white cover, and putting in the new cover. Much easier than installing a modchip.
This is about the same as unscrewing controllers and switching the colors around.
For those custom cases with the LEDs, just follow these instructions:

P.S.
As always, make sure to read all the instructions before hand before attempting to do anything.
