Option b of course, rent cheapest vps, ionos.ca offers plans for 2$ per month, it’ll be cheaper than Google fiber, you can also use sshuttle https://github.com/sshuttle/sshuttle on your openwrt router and connect everything to it be it by cable or wireless, then Nintendo gaming will also have that port forwarding because your whole traffic is going to go through vps

Problem is, new i7/i9 top out at 24 pcie lanes so old xeons is still bang for the buck in homelab sector

Mining boards give about 1-2 pci lanes per gpu because there’s a lot of gpus, also look up Nvidia mining gpus, they restricted to pcie x1 or/and x4 even if you put them into x16 slot

Chinese mining motherboard with any xeon cpu (because of abundance of PCI lanes in cpu) and 12x16gb nvidia p100 and nvlink bridges (p40 gives 24gb of vram but doesn’t have nvlink capabilities and slower gddr5 memory, p100 have hbm memory on the contrary which is good for llm) and 8x64gb ddr4 ecc ram, if you buy gpus from ebay and other components such as motherboard, CPU, ram, and ssd from AliExpress it comes quite cheap

Hi-end Xiaomi router, they have WiFi ax and enough ram and support open wrt so you can host your things on it, better yet, do DIY router on orange pi board, there’s tutorials you can follow
