Only shop in the Grenoble metropolitan area with a PC in store stock.
Very appreciable when you are in an emergency.
This mini PC works wonderfully; what’s more, it is Linux (Ubuntu 24.04) compatible, as mentioned by the manufacturer. It is very quiet, even when the fan starts up (generally for a short period of time).
A tiny but very well-equipped PC.
Fast and quiet hardware. Even the fan is not annoying: it starts up from time to time but is not loud. It is reminiscent of the DVD players of yesteryear but much shorter and much quieter.
Highly recommended for small spaces.
And thanks again to the LDLC team at the Grasse store for their excellent advice.
The product was received on time and was exactly what I wanted. The ordering process was simple and the website clear.
