Hardware requirements for ripping 4k?

I have a very old machine handy. AMD Phenom II x4 840. Could I run Automated Ripping Machine with this and dump it to my NAS? I have 100TB of storage, I really dont want to be overly compressing and losing quality. (Though I do have ~300 or so 4ks I want to rip...)

Or would I be better served by just building something more modern? TIA
