Most wifi 5 routers have bad security issues, latency, crap QoS and, a lot of Wifi 5 chips don't have the hardware acceleration needed to be useful anymore, and if they're not supported by firmware like OpenWRT they're mostly just e-waste/bot net boxes. I seen wifi 7 routers going for 25$ where i live they don't have 6Ghz.
I download Fedora 42 KDE and clicked like 4 things to get my system working well with Steam one was the Nvidia repo, the other was the Steam repo, and update and reboot.
skip the Cache Drive and use 2 Drives for the main OS, if you can get ECC as 20TB's is a lot of data if something goes wrong, and like other file systems ZFS will destroy your data with bad RAM.
You will need a good 10Gb nic, I have been using Intel nic's if you use a Intrusion Prevention System that can eat away at the CPU, also more RAM helps like 8GB's or more for IPS, I use 16GB's for IPS + ZFS and a nice Switch can help a lot as it can do DNS and the works, more or less i use a firewall box to a Switch and use a Layer 3 Switch for routing, some can do 20+Gb's routing.
