My personal experience with PCs has always been with various models from the Lenovo range (Thinkbook(?)), always bought used/refurbished from eBay.
They tend to be designed for business use and consequently of solid construction. (Good reviews.)
I'm still not a fan of Windows 10 (yet) so would go, for instance, for a T420 (not the "s" model) with Win 7 on it. 8GB and 7200rpm or SSD drive.
I configure all networking OFF, and transfer files via SD card or USB/eSATA hard disk.
So far, so good. (Fingers crossed) ;-)
It's worked, so far, for me.
