I used to build all my machines but no longer do so because I get so 
many cast-offs.

My newest one is an 8 core i7 3.8 ghz
It runs Win10 incredibly well and Win11 too...but I had to do the hack 
to get Win11 installed>

My main Linux machine is a quad core i5

That particular machine was the *only* one I ever purchased already made 
and I felt guilty. I was going to build one but this was offered on eBay 
with no OS at a price too good to refuse.

It was packed wrong and the case was crushed in shipping but all else OK>

I notified the seller and since there was no way I could make a claim 
with the shipper, he offered me a nice partial refund when I told him I 
could re-case it.

It was a bit non- standard and I had to do a bit of modification to get 
it re-cased...so I consider it a home built machine and no longer feel 
guilty. LOL

Anyway as the the 8 core machine, though I do have Win11 installed on a 
drive, I'm not using that...I'm fine with Win10

When support for Win10 ends, maybe by then I'll have a board that 
officially supports it.


I use the Win10 machine for scanning and doing professional quality 
prints and don't need to even keep the machine on-line.
