Apple has declared the end of the 20-inch 2.1GHz PowerPC iMac.

While the product remains available on the company's UK store, a note to resellers distributed today declares the product officially, "End Of Life".

"With immediate effect, the following product and it's relate configurations are "End of Life" (EOL) and no further orders can be taken," Apple explains.

If you have made a pre-order of the product, Apple warns that all outstanding orders "for which no stock is available" will be cancelled. The company isn't automatically revising existing orders to the new Intel-powered iMacs.

Apple has now migrated its pro-portable, the MacBook Pro, the iMac and Mac mini to Intel processors. Widespread reports claim the company to be speeding ahead of its original transition plans.
