Building an OPNsense router (sopuli.xyz)

I am thinking of building a router for OPNsense. I am familiar with building computers but I am not familiar with networking. What kind of hardware would I need to hit 1, 2.5 (my most likely target), 5 or 10 gigabit speeds on my local network?

I was thinking of buying a small form factor PC and sticking an Intel I226 Network Card or something similiar in it.

So, what kind of processor would I need?

Depends on what features you want to enable and how many devices are using the network but a relatively recent quad core above 2ghz is probably plenty. If you want to do packet inspection or such, more Is probably better but you're not going to need a 32 core or anything. Is there a specific reason you want a 5gb local network, or just want the fastest network you can afford?

I was targeting the 2.5 gb/s local network, as I am starting to have equipment with 2.5 gig ports, so I might as well make use of them.

Consider buying dedicated firewall hardware - check out "DEC677 – OPNsense Desktop Security Appliance". I don't have experience with opnsense hardware but I use similar for a different os. The idea is that you won't run into compatibility issues since opnsense will test all updates on their own hardware before releasing them and should be optimised, etc.

Thanks for the redommendation, those look quite nice, but are quite pricey too.
