I really wish I didn't give away the Dell 316LT I came across a number of years ago (~2008?) at a swap meet. I had the whole kit - 386SX16, 8 MB of RAM, extra screens, the manuals, an external 5.25" drive, and all the diagnostic disks. But, my parents were moving us from a large house in Alabama to a small apartment in California and we didn't have the space for most of my parts (cough e-waste cough) collection.

Teenage me had no idea what to do with it. I didn't know how to compile a Linux kernel from source, at that point I'd barely started moving beyond Atmel AVRs and Java on LEGO Mindstorms.
