Help Needed Please

I am not really into Pc's but I am into hi fi and music. I currently use a 2019 Pentium i5 NUC with upgraded ram (32g) and have everything on a new 2 tb SSD. I am wanting to upgrade to a new NUC with maybe s lots for SSD's, as was told to have a small one just for the OS and the My Docs and My pics and save the other slot for either my own 2tb SSD (or another) for just the My Music folder, that I have "ripped 800+ CD's to. Question would be, is this possible? if not, what small PC could I get?
I have a good pc au fait chap who can put all together for me, as I am mobility impaired now
Oh, budget. About £1000 or there about
