IBM thinkpads as far as I know are somewhat sought after, but for the most part they're just a part of the sea of old hardware that's too new to be really considered vintage, but too old to be anything useful. Things like even old Dell Dimensions from the early 2000's may never really see the vintage charm as something like an IBM PC XT or other, mainly because of the dime a dozen existence among other things. In a weird way, they're still somewhat connected to modern computers. However, some people absolutely love them and collect them, so that's the niche you'll have to cater to. Vintage hardware has no practical use, you just have to find someone who'll want em Look online and see what they have/are going for, maybe they might be a little bit more than what you think they're worth. I personally really enjoy collecting vintage hardware (I've got an IBM XT 286, one of or THE rarest ibm PC ever made), so just see what you'll find!
