I mean if you can afford it then go for it but I was just saying don't buy something expensive just to run a firewall. Heck I'm running my pfsense as well as pihole, home assistant and an app serv all in VMs in an old micro server, dual core CPU.
You can find refurbished enterprise grade servers on Amazon for like $200. If you havee somewhere to put it why not do that and you can have a full blown media server also.
E.g. This one with 2 X 6-core CPUs
Enterprise Proliant DL360 G7 Server | 2 x L5640-2.26GHz 6 Core | 48GB RAM | P410 512mb | 3 x 300GB SAS (Renewed) https://www.amazon.com/dp/B07VGM4V84/ref=cm_sw_r_cp_api_glt_fabc_MKZV0QNE5G2SJK4NEFT9?_encoding=UTF8&psc=1
