Quite a few months back, we made an article which gave details on a supposed sale of a Durango alpha tower. The seller, known as DaE, put the alpha tower up on eBay.

But after some time, DaE has put another tower back up on eBay yet again. Listing some of the details of the specs - with the message on his twitter "Last chance to own a piece of next-gen gaming history!"

Here are the specs which are listed on the eBay page:

Processor Type: 8-core 64-bit CPU
Processor Speed: 1.6 GHz
Hard Drive Capacity: 500 GB
Memory: 8GB
Primary Drive: BR 50G

Other sources believe the Durango tower he is selling may actually be authentic.

For those who do not know what the Durango is, it is the next generation Xbox which is still awaiting announcement. This is NOT what the console will look like either. This is called an Alpha Tower. It is in no way close to a final product.

Here is the link to the eBay listing if you want to check it out.

The previous Durango alpha tower he was selling eventually sold for $20,100. He is currently in talks with someone attempting to sell it at $3,000.
