I really appreciate all the advice, but I am not going to build from scratch again (but I will encourage my grandchildren if they ever get interested). In that vein, the link on the modern build-your-own case (Fractal Design) from David was very helpful--thanks!
So, if I need a new in-home server, I think I will go the Dell route. The multiple easy in/out drives capability is just what I need for my redundancy case (and ease of use) and assume I can add SSDs from my own sources instead.
Best regards, and thanks again to all of you,
-Tom
