Got a young guy that needs a reasonable used laptop, in the $2-300 range. Looking for smooth but not spectacular graphics, and a 15" screen or better. Preferably with 2 drive slots so he can have an NVME or other SSD for the OS and a large rust drive for installing games. It’s going to be plugged in when used, and weight isn’t a great concern, it’s just for travelling with.

Any suggestions on what to look for on eBay?
