120GB can also hold a whole library full of music and/or books, so that's nothing to scoff at!

disposable vapes have a lithium ion battery and usb c port for charging… it’s not hard to turn one into a battery pack for something else that took batteries, like a flashlight
SSDs, even 120gb ones, are definitely useful in this day and age. A year ago you could just buy a brand name 120 or 500 gb SSD for cheap for throwing into an old PC. Now a days a new 500gb SATA Samsung SSD is $274 CAD.
Yeah, you can buy a cheap USB-to-SATA boards/cables (or enclosure) and use them as USB drives. I have an rPi booting off an old SATA-HDD (more durable than micro-sd in my experience). Unraid supports arrays with mixed sized disks too, so you could make a NAS.
Just to add:
Various cheap LCD panels can be repurposed using a $10-20 driver from Ali or eBay.
Red LED 8-segment displays from old alarm clocks - fun to use for any other purpose using a microcontroller.
I think it was an old toaster I got a nice slide variable resistor from.
Precise (but weak) stepper assembly from old CD/DVD drives.
Standard cords from any appliance. Nice high-current switches.
Some old keyboards (especially programmable ones) have a DIP chip, if you are into building keyboards.

When a Thinkad is disassembled, there are like 20—40 fragile pins on the connector. I always just assumed it was custom and proprietary. Although it probably would not make sense for IBM to be in the LCD business, so I guess the pins must be standard (probably not the connector though). From there, can I trust the wire colors?
I ask because sometimes I find a destroyed laptop like a keyboard and base busted in half, where the LCD could be salvagable.
The most recent trashed laptop turns out to be purely the display, which was torn off, scratched up, and hanging by a wire. The power connector was smashed. But I got a Thinkpad docking station which supported an external display and a new power input, and it works just fine. It is now the fastest “desktop” in my house.

I had to look into how that’s useful. Apparently printers, engravers, and laser cutters are made with them. Requires a lot of ambition but if I really need one of those things and I hate what is in the enshitified marketplace, it might be interesting. I imagine the difficulty is in all the other components needed for those things.

I did not know that was a thing. I have lots of spare keyboards and thought of using the linux app keyb to map chars like ½, “, ”, etc. to it. Thanks for the suggestion, b/c I think my plan of having two keyboards in front of me is a bit wasteful of desk space.

AFAIK high-resolution screens (laptops, tablets) often use LVDS interface and connector, thin wires in twisted pairs. Like this one
Do you think you could put together a guide on what to look for in these parts for someone who doesn't really know anything about tech? I'd really love to learn and I feel like ripping open a busted laptop would be a great way to start, but I don't even know what "female barrel connector" or "OEM PSU" means. "160gb SSD" though, I know that one. That's so many damn photos. My partner always shoots JPGs because storage is expensive but I always shoot RAW if I can...
