Hi Luca,
I have a GM811G, but I think I can help answer a couple questions about the cables and power and the answer is no. It doesn't have a DC socket or any type of cable management. All the cables will be hanging out. The CEM70 might be a better choice if both of those are important to you. I purchased a Losmandy because I liked the way it looked, the build is very, very solid and well made, it's upgradable, they have fantastic customer service, and most of all, it's made in the United States, Burbank to be exact. I'll pay and have paid the extra cost for well made tools made in the U.S.
