You can get a newer PC on ebay for less than $100. New enough to have originally run Windows 7, 8 or even 10. Most are off lease and so they can’t put windows back on them because the company bought a bulk license and those can’t be transferred. That’s why they either won’t have an OS or will have Linux installed.
Here’s one; Dell Inspiron 660 Core i5-3330 3GHz 750GB HDD 8GB Ram Linux Mint - Originally had Win 8 on it. Should have a wifi card in it. Loaded with ports to plug in most anything. SD card reader, several USB ports including some USB 3.0, HDMI port.
Ought to scream with Linux Mint on it @ 3GHz. $89.99 plus shipping from Kansas. Seller has 100% positive feedback.
I’d buy it in a heart beat.
The machine I’m using now is an older (circa 2005) Compaq SR1900NX with a 3.3 GHZ processor, I have a couple ~120 GB hard drives in it, it is a 32 bit machine. It is ethernet plugged into my modem (xfinity) but because of WinXP limitations, FTP download fails for anything bigger than 2 gig.
