I used to roll my own. But my brother is in IT and gets me three or four year old ones that are good enough. And I’m a power user (not gaming though).
For most business stuff, or databases, you don’t need top of the line.
I agree completely. The primary reason that I am considering spending a considerable amount of money on a "gaming pc" is for flight simulation. Although, I do have 7 tech savvy grandkids and most of them love various types of games on a decent computer. I like it that I can afford many good PC games for them that are highly discounted because they are not the most current releases.
I purchased two HP Elite 8300 Ultra Slim desktop computers in 2019 to use to connect to some 1080p TVs to play and record videos from streaming services using a program called Audials. I also use them as Plex media servers. Even though these have just 3rd generation core i7 processors they still work fine for this purpose.
They were around $150 back then with new SSDs. They are now less than $100, because their competition now are the tiny little PCs that will basically fit in your hand. I will probably end up purchasing something more modern to use with 4K, but with the limitations of my Comcast account using 1080p is much better for keeping from using too much bandwidth.
