I gave it a shot and its just too loud for my house - can't have the kids being woken up because of the machine.  I have selling history on Reddit and eBay - looking for a trusted method of sale for both parties.  I see these being sold for around $5500-$7000 on eBay.  I'll offer this one which was used for only 18 hours for $5000.  No problems with the miner, runs at advertised speeds.

Edit - Lowering the price to $3500.
