Has anyone had any experience with shinobee? Is this a decent PC?

My boyfriend is looking to get a new PC, but neither of us knows much about PC building. He has decided to go with a pre-built one and found one he really likes. Here is the link to the PC he is interested in: link

I’m wondering if this is actually a good deal. shinobee has a lot of negative reviews on TrustPilot, so I'm kinda skeptical. Are there any other reliable websites in Germany where we could buy a good PC?
