There's literally only one red Asus S6F laptop on the planet, and if you want to avail yourself of the opportunity to win it - and do some good into the bargain - visit eBay or Harrods this weekend.

Asus is offering the machine for auction, with bidding taking place online at ebay.co.uk and at retailer MicroAnvika's store-in-a-store on Harrods' third floor. The one-of-a-kind laptop will go to the highest bidder while all the proceeds go to Comic Relief.

The notebook is clad in red leather and comes bundled with a suitably hued mouse, mousemat and carrycase.

The auction kicks off tomorrow, Saturday, 31 March at 3pm BST and ends on Monday, 9 April at 3pm BST.
