I don't think I ever got a prebuilt pc which didn't have crapware coming with it.
Most of the time, the crapware was easy to disable (or delete) by hand.
The most annoying crapware I had to deal with, were trial copies of mcafee antivirus which would repeatedly spawn every time I killed the...
Same here.
Most of my "rebuilt" desktops, is putting together scrap parts I have accumulated over the years from old computers given to me.
I usually end up running Linux or one of the BSDs as the operating system on these rebuilt units, and not m$ windoze nor maco$
This is what I would do nowadays. My next desktop will likely end up like this. The old style hard drive will be largely a drive for backup of personal files and some system stuff (such as c:/windows).
Currently I use external hard drives to do periodic backups of personal files.
(Speaking in terms of hypotheticals).
The only scenario I would ever buy a "refurbished" desktop computer, is if the hard drive is brand new.
I generally don't trust second handed hard drives under any circumstances.
With a lifetime experience of being given a lot of older machines, I have come to the conclusion that refurbished computers are largely a waste of time and cash. In addition to headaches of troubleshooting vagarities of older hardware.
Easier and less headaches just buying a new desktop machine.
