I was listening to Widows Weekly podcast (Episode 837) and Paul Thurrott advised that the mini computer line by Intel – The NUC – was being discontinued.
The Verge has an article here https://www.theverge.com/2023/7/11/23790956/intel-nuc-compact-pc-discontinued
I have two NUCs and really like them. Not only are they fully functioning computers in a small size, but you can configure them yourself to some degree.
On the other hand, many prominent PC makers now produce small form factor computers and, with these, you are not confined to an Intel CPU.
I am attracted to the Asus PN 64. Like the NUC, you can get a “barebones” model and configure it with your own selection of DDR5 RAM (up to 32 GB) plus two hard drives – one M.2 and one SATA – just like the NUC.
The Asus PN64 supports high end graphics and has plenty of outlets including a handy “configurable” port that can be set up for VGA, Display Port etc plus HDMI 2.1. https://www.asus.com/au/displays-desktops/mini-pcs/pn-series/asus-expertcenter-pn64/
