Several of my computers including one I built myself in 2008 is still totally functional. I could probably install a new 64 bit is and keep it running. I originally installed Windows 7 pro 32 bit due to how stable it was.

The problem is technology is moving forward so quickly anything you build or buy today is antiquated in less than 2 years.

With that in mind, rather than doing the upgrade to the old build, I simply purchased a rehabbed Dell from the Amazon rehab store. It was loaded with W10 and halfway decent specs for somewhere around $400. It's what I'm using now and it's doing a good job with very few problems. It came with a wireless mouse and keyboard. I use a HDTV for the monitor.
It's set up for music recording but also has access to the Internet.

My studio is on a farm so talk about dust? And spiders? Yep. I reckon I need to bring my portable air compressor to the studio and blow out the computers.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
