Well here's a little expensive but very well finished and food sold by a registered connue.Les cables (all wrapped) are long and the number of shots is largely sufficient for an office PC or game mono GPU (note the maximum power, no high-end graphics card!). Silence is not perfect, but quite bearable for a PC placed on the ground under a bureau.En However, in a very quiet room, we hear the hum of the fan .So, do not let light into a room at night!
