This is more or less a question of economics and saving valuable time. If you need Marius, you probably know that technical support for dedicated servers and even managed hosting is horrible to non-existent in most cases.
You will be able to save a lot of time and frustration by working directly with us. Since we take on only a few clients and Marius knows each client and his/her servers personally, Marius can offer personalized servers administration. We are available 24/7 for emergencies, and you will always deal with us directly. No middlemen, no other people. Just us.
Furthermore, you will actually be able to save money in the long run. What good does it do that you saved a few euros by buying the cheapest server on the market if it crashes all the time or you can't get hold of anybody during emergencies? In Marius's opinion, his service more than compensates for the price you pay because of higher uptimes and because of the ease of mind of knowing that you can always count on somebody reliable to maintain the servers and give you advice.
