Yeah, I’m not so sure either.
I mostly just played around with it because some application I was testing relied on s3 storage and Minio was the best selfhosted project I could find that was s3 compatible. Worked pretty well, from what I can remember.
I’m using a thinclient (Fujitsu S920), slapped an Intel Pro/1000 NIC in there and installed opnsense. Hardware cost for both used was around €80. Wifi is handled by a TP-Link access point.
It’s a big boy router/firewall, and it’s been quite a learning experience but very fun.
