Very cool. I recently was given a 2015 21" iMac with no screen that I am going to fix and a 2011 iMac with a HDD that works and I am going to replace the HDD with a SSD.
I have an old 2015 MSI laptop 17" that I run various versions of Linux on and several other older Windows machines and an old Asus tablet running windows 7 with touch and stylus.
I look forward to your further adventures and nicely done.
