Reddit co-founders, Steve Huffman and Alexis Ohanian, sold their company to Conde Nast at the end of last year. Now they’re planning giving their laptops a liquidity event.

They’re placing the two Apple G4 Powerbooks (12″ and 15″) used to start Reddit on this eBay auction. 100% of the proceeds are going to the American Brain Tumor Association.

The laptops come adorned with all those super-rad Reddit alien stickers Alex designed and the palm imprints of the founders themselves. Alex guarantees “it will at least double your already obscene valuation”, but notes “Luck not included”.

Bidding is starting at $300 + $60 shipping and handling.
