    I ordered twice. The first one didn't work. After contacting the store, I returned it and received a refund. I ordered a second time and this time it's fine. The only downside is the screws at the disk slots are very tightly fastened, which needed to be carefully unscrewed. The second downside is the way the package is packed in Spain. They just provide a bag. The computer is fast. Temperatures are okay.

    Arrived extremely quick. The packaging is of very high quality. I put 32gb ddr5 5600 and installed cachyos with steam. Games run really well in linux. 60fps on arcraiders @ 2560x1080 which was surprising. Left the metal shroud for better airflow and seems to run fairly cool. It has space for 3 nvmes which i was pleasantly surprised. When i have some time i will try to connect an external gpu with oculink which should make it even faster.

    Delivery on time. Product as described.

    Processor performance is similar to a 7735hs (other minipc owned) and temperatures are lower (max. 73c on cpu and 39c on ram) since this one uses a better cooling system due to an increased dimensions which allows a bigger secondary fan. I cannot test 3d performance but it would be the one expected for a 780m igpu being greater compared to the 680m on the 7735hs.

    Installed windows 11 ltsc iot without issues and all drivers have been downloaded using sdio (snappy driver installer origin) through an ethernet connection, then the wifi and bluetooth devices are properly recognised.

    Good value for the money (226€ barebone model)

    Delivery from Spain was very fast. The item has had a rough journey. Fortunately, the packaging offers enough protection. The item was barebone and I equipped it with one 32GB DDR5 5600Mhz module from Crucial and two SSDs from Crucial. What stands out is that the device is easy to set up. No complicated configurations. The device will be used for Proxmox.
