How much current can I put into my RPi?

What is the maximum current (supply of) that can go into the RPi before you do serious damage? Would a 5v 2.1A adapter benefit me in anyway if I am using:

15m Ethernet cable

USB flash drive

mouse + Keyboard

HDMI screen

and have overclock the device to ARM=932MHz/GPU=350MHz/RAM=500MHz

... Instead of a 5v 1A charger?

The Pi will only draw the current it requires. However there's a polyfuse on the input that limits the possible current. If the Pi plus any usb devices exceeds the threshold then the fuse will 'blow' and the current will be limited.

Supplies of this sort are constant voltage, variable current up to their rated values. So your 5v 2.1A adapter will (in theory) supply a constant 5v at any current between 0 and 2.1A. You're not forceing 2.1A into the Pi, so nothing to worry about. You could happily use a 5v, 100A supply and the Pi would still only draw the 500mA or so that it requires.
