The noise complaints are numerous. So why doesn't Spondoolies address this issue and make an alternate version in a 2U rack size? I'm sure they would sell more units if they weren't so loud.
I thought my cointerra was obnoxious. Unless you have a room at the far end of your basement, this is not for you. I was really hoping to let it vent out the window. It's just to damn loud.
My SP10 is in a quiet rack cabinet:

Basically have two choices. Throw it in a data center, hopefully a friends or if not then a regular co-location center or a high quality acoustically sound sealed rack. I would imagine 1/4 rack of good quality would be $1200+. Almost evens out compared to co-locating. And there is something nice in your mind knowing all your noisy, electrically sucking hardware is safe and sound in a DC. My poor home only has 100AMP main circuit, but it is a small 3 bedroom ranch style place. No corner basements to stick a cabinet in.
Or, if you are really into it and have the property space is to build some kind of shed and feed it with it's own electrical box from the electric company for all the power you need. Of course air conditioning on a 24/7 basis. This is an expensive way to go, but for people that always want their own gear in front of them.
