Hello, Habr!

In the life of every person, the need for a computer upgrade sometimes matures. Sometimes it’s buying a new phone instead of a broken one or in pursuit of a fresh android or camera. Sometimes - replacing a video card to pull the game at a minimum. Sometimes it’s installing an SSD in a laptop on which you tied a tenth of Windows, but she doesn’t really like to live on Core2Duo and 2.5 gigabytes of addressable memory, and she constantly unloads unused pages into a page file, destroying the already not-so-fast transfer speed with 32- gigabyte drive.

The approximate cost of ownership is 3.89 rubles / kW * h * 0.8 kW * 24 h * 31 days = 2315 rubles / month. But this is if he will thresh to the fullest without ceasing for a month, which I doubt very much for the reasons for the lack of such tasks and the survivability of iron. For comparison, the cost of renting a similar server from quality parts is about 25k rubles / month.

I think this is a very good server for the money.
