Looking to build my first server out, trying to figure out if there is a "better" platform for my needs. Right now I'm just planning a mix of machines and containers in Proxmox for running a NAS and Plex server, router of some sort (also, any preferences on wireless access points?), a pihole if that's not just as easily done in whatever router OS I decide on, VPN, and 3-5 various machines/containers going in and out of service as I find what my needs else I want to play with and host continuously..
Basically just looking for bang for the buck CPU/chipsets people are getting for this use case. Any advantages of AMD vs Intel in mid-consumer level options? Is getting something similar with more efficiency cores worth worrying about in a hypervisor use case?
Yeh, Id second running it on whatever you have kicking around, and figure out where to go from there.
Refurbished SFF PCs from ebay are quite popular if you dont have anything to hand. Easy to pick up a 4 or 8 core CPU, load it with ram and pop in an SSD. Onboard NIC will be fine until it isnt. Integrated graphics for transcoding is fine until it isnt. When they start becoming a problem, figure out your next step.
Can always repurpose the old hardware as either an additional node or as a proxmox backup server.
Edit: only thing i will say: if you are virtualising opnsense (or whatever as a router), its worth getting an intel pcie 4-port network card. It will let you "bifurcate" the 4 ports, so you can do pcie-passthrough to opnsense for WAN and for LAN (home network), and virtio the nic for proxmox bridge
The multi port NIC can work, although I would recommend jumping straight to a managed or enterprise switch that can do VLANs. It saves on physical wiring and a managed switch often overlaps with other desired homelab features anyway, like PoE, IGMP/MLD snooping, and STP or loop-protect.
Its more about having physical separation between wan and any of your networking. Removes a potential avenue of misconfiguration, and means you dont have to debug switch config, proxmox bridges/firewalls etc if your internet goes out.
Having a physical port for lan means it can adopt the default anti-lockout rules of opnsense (pfsense has similar). So mistakes on the firewall doesnt mean bricking your network.
And passing them through via pcie passthrough means you can never accidentally join a VM to the wrong bridge.
