I've finally got a 486 in my collection.
It was an Ebay auction win.

A Sound Blaster 16 Value ISA card
A Vesa Local Bus S3 Video Card
A peripheral card (parallel and serial)
A network card (ethernet and some other serial connector)
A CDROM Drive (not sure of speed) - working
A HDD (not sure of size) - working
It also came with a Vision Master Pro 450 monitor. This weighs a ton.
And there was some barrel battery leakage.
The packaging was awful. A reusable carrier bag and bit of bubble wrap.
I've taken the battery off. I'm looking to install a coin battery slot.
The case is a little bit scrappy in places, but it has got a working LCD, reset and turbo buttons.
