Thought I'd chime in again to say I am building a new system for our household.
DW is starting a new job soon, which has the opportunity to work from home from time to time. She currently has a ~$200 ARM-based ~12 inch Chromebook as her only computer and I have a ~$400 dollar Chromebook Intel-Based (with hyperthreading off its a 2 thread machine). We've had both machines a couple years and the prices where what we paid for them at the time.
Both machines handle web/email/youtube well, but can struggle outside of the day-to-day. Based on that we decided to add a dedicated workstation to the household, to handle remote access, video conferencing, and document editing with reference materials available on screen 2. So I will be building a dual monitor setup powered by a Ryzen 2400g, (technically last generation, I suppose) on an X450 motherboard, with 16GB of RAM, an M.2 boot/Office Suite drive, and a 1TB 5400 RPM storage drive. (oh and running Windows 10 Pro to avoid as many compatibility issues as possible).
I could have bought a pre-built machine for around the same price and she would have been just as happy, but I am using this as an excuse to scratch the itch at no additional cost.
I briefly thought about making it a shared computer, throwing some extra cash at it and making it more of a gaming computer. But I realized that would increase the cost several-fold and realistically by the time I would have time to game again it would be time to upgrade anyways (at least GPU).
I had to fight my old instinct to buy the biggest and best under the assumption that it would remain relevant longer, as the past decade or so really has not seen my computer become outdated as quickly (outside of running AAA games at maximum settings).
I am looking forward to my first build in a long time (our last desktop was a full sized case with a CRT monitor that we pulled out of a closet and disposed of when we moved in 2009 and at that point it was probably 8 years old).
I also look forward to some degree of upgradability (RAM, a few more options of AM4 processors, discrete graphics cards) to keep the machine relevant a longer (rather than the non-upgradable disposable nature of laptops now).
