I bought this about a month ago to use it as a ProxMox server and indeed it does the job accordingly. Generally I like it and I would recommend it for this purpose. I am only going to explain why I did not give it 5 stars: I tried to upgrade the nvme inside, but for this particular model, I think it requires a special key which I do not have. I also think the nvme are mounted upside down and the heatsinks for them are not as effective. It runs a little hot and the case is made of plastic. It is not whisper quiet, you can hear the fan, but since mine is a server located elsewhere, it does not bother me much. Other than these I recommend it. I cannot talk about how good the customer support is, but I will be llooking for this brand for other builds in the future.
