Caution!

Tuning up to extend, exchange or remodel PCs and PC parts should be done at your own risk. If you failed to follow the directions in these articles, the responsibility is yours alone.
Tuning up voids the warranty from Apple com.
Never forget to turn off the power and unplug your machine when you begin these operations.
Since static electricity may short out sensitive electric parts when you are working, please ensure that you drain static electricity by touching a grounded metal item, such as a tap or water pipe prior to touching the Logic-Board, Memory and Hard-disk. Alternatively, you could use an electric wrist band.
NEVER NEVER NEVER touch the CRT-tube or Analog-board when you remove the Rear-cover. These are very very dangerous because they store thousands of volts of electricity. The CRT-tube and analog-board are HIGH VOLTAGE!!!!!!!!
Never ask PC shops to tune-up any Mac products, eg increasing the resolution of ColorClassic or clocking up of LC575 Logic-board. NEVER use these tuning up techniques commercially. (ie do not sell anything you have tuned-up).
