Buy once, cry once?

Slowly acquiring hardware and trying to know where a starting limit should be set, kinda analogous to avoiding feature creep. Want to setup the house and my initial rack with 10 Gbps connectivity. Yeah, it’s nice to setup a small 10” rack, but give it a year and I’ll need a standard 19” rack, switching vs routing and hardware to support it; stuff just grows. How does the Mikrotik CCR2004-1G-12S+2XS look as an initial backbone? I know my way around RouterOS and it’s Linux vs Windows/macOS compared to Ubiquiti where I can go in and tinker with every little thing and learn more about L2 & L3 networking, performance, and topology.

Initial plan aside from standard self-host all of the things is to house an all SSD NAS (I have a dozen or so 4 TB SATA drives) and will be building out a high availability cluster. Not sure if I’m PXE booting thin clients or having dedicated gaming computers, but hey, that’s what a homelab is for, tinkering.

What other 10 Gbps hardware might I consider over the CCR2004? Is there hardware than 2x (arbitrary) the price that’ll give me notably better performance? What are some caveats I should be aware of in implementation or planning things out?
