And what's with the obsession with aesthetics? You spent a bunch of money on fancy cable management and patch panels, but you're still using a bunch of ugly, exposed cables. It's like you're trying to make a statement about how much money you have, rather than actually building a functional network.
And don't even get me started on the DNS settings. You're using a custom domain name for your Synology NAS, but you're still using DHCP to assign IP addresses. What's the point of having a custom domain name if you're just going to use a dynamic IP address?
I'm not trying to be mean-spirited, but this post just reeks of "I have a lot of money and I want to show it off". If you're actually interested in building a functional home lab, I'd be happy to offer some advice. But if you're just looking for a way to justify buying a bunch of expensive networking gear, then maybe you should just stick to playing with your toys.
