Since it has been stone reliable over years, I'm keeping my R-PI / WD 4TB USB drive combo until the 4TB drive fails which may take years... And while the purists will complain about Rsync's down sides, it's worked well enough for me.
I feel the same, the Pi works, it's doing 1 specific job and I can leave it run overnight

Wow you have been busy...re the carpentry trim I noticed that when we went to see the wife's pen friend in Cincinnati we don't do that in the UK just skirting boards (baseboard) the windows are never trimmed. I understand what you mean about the baseboards though, in our last house I removed them, laid the floor, then re fixed the baseboard, much neater and no ugly 'trim' to install.
Looks as if we're going to replace our windows, remove the old wooden ones and replace with double glazed UPVC, to replace with wood double glazed is just way too expensive. Also want to replace the hob and oven in the kitchen, want to remove the gas hob and install an induction and a self clean oven it's all built in as well so I'm hoping I can find like for like in sizes.
