Need help verifying a hardware spec

[robgalpin]

Hi, Apologies if this is the wrong forum to ask this question. If this is the wrong place to post this please tell me where would be more appropriate.

This is about making sure the computer purchase I am making won't leave me wanting more and needing to buy more to make it work as needed.

My experience is that the Pro Tools documentation describes minimum spec but there are so many details beyond the spec that need to be right in order for all to work well in a specific setup.

I use an MBOX PRO interface - FireWire will require adapter to Thunderbolt, right? It is a home studio. 99% of use is just me recording tracks on at a time - but sometimes need to record a drum set - midi drums with 3 or 4 mics on live cymbals.

I am looking at a refurbished iMac, originally released June 2017 - see detailed spec below. Will this work? Anything to look out for? Thanks - and sorry if this is the wrong place to post this. I was surprised that I could not find discussions on this board about hardware specs - pitfalls and whatnot.
