There's a ton more stuff I have lying around that I can't remember off the top of my head right now.

Wow - that's a lot of stuff 😳

IOmega Zip100 drive
Sound Blaster 16, Vibra ISA version (I forget the actual model number)
NVidia GeForce 3 Ti500
NVidia 5200 FX AGP- I use this as a spare business graphics card in times of ruin or turmoil
numerous floppy disk drives
52x PATA Samsung CD-R/RW burner

Edit: most of this stuff is "retired" but still working, sitting in my closet in anti-static bags, awaiting Ragnarok/Judgement Day/Duke Nukem Forever 2.

I got too much stuff to bother making a list but there is a lot of modern and vintage hardware in there. Even a evga 8800gtx and two gtx280 would easily make the list.

386-DX board - DOA, hanged on a wall
Chaintech 486SPM board - DOA, hidden in the cupboard
Radeon 8500 - working, gifted to a friend.
Gigabyte 8PE800 with 1700Mhz Celeron, 1024Mb RAM and Radeon 9600XT - sold to a boy in the neighborhood, still works
Radeon x1800GTO - worked a lot, now half-dead, hidden in the cupboard

Only thing i ever junked was a working 386 computer years ago, before i started collecting retro computers. Now i bitterly regret it.

I am glad that I am bit of a hoarder although there isn't enough out there to be a problem collecting wise. But when someone comes along and you don't like it or really want it its best to take it and put it somewhere out of the way. Never know what all there might be or the need for something down the road.

That is why I'll likely not trash those socket 7 boards I retired. With a slower pentium processor, they could be used for DOS.

Not exclusively "mine", but we still have a ton of our old hardware. My dad throws very little away unless it's totally burned out (we're currently hanging onto a couple questionable Nforce 2 Athlon XP and Dual athon XP boards for that reason). We've still got a large number of our old sound cards, video cards, mobos, cases, monitors, etc going back into the 80s, though mostly stuff from the mid 90s onward. I'm not sure what happened to the old 486 and 386 boards, they may be gone or in storage (he may have traded/sold them back in the 90s or they may have died and gotten recycled), but a fair bit of Socket 7 stuff (a bunch of CPUs and one working FIC 503A system),
Socket 370 boards and CPUs,
several slot 1 CPUs and 1 slot 1 (i820) system,
a bunch of AGP video cards, a couple PCI video cards (Rage Pro, Stealth 3D 2000s, maybe others),
at least 1 ATi 16-bit ISA SVGA card,
a bunch of PCI sound cards and a Pro Audio Spectrum,
and XT clone keyboard and a couple AT keyboards (the nicer of which I gave to Apolloboy for his P200 system . . . ironically an ATX board using an adapter in this case 😉)
An early 90s 14" VGA monitor, a 19" workstation VGA monitor, 20" CRT Mac workstation monitor from the early 2000s (using standard VGA connector), a 17" CRT VGA monitor from late 90s or early 2000s, and a few GEM LCD monitors. (VGA only, 1024x768 native, pretty good picture for their age -and analog to digital nature, and one of those is still in use on our main shared family PC)

We has even more a couple years ago, but we've gradually gotten rid of some of the more definitively non-usable things, like (very) old sever components and some proprietary hardware originally from work. (some stuff from integrated solutions, among other things -we still have some Sun and SGI workstation keyboards) We even had the old 14" grayscale VGA monitor from my original PC up until a few years ago. (that machine was a bit of a contradiction . . . a mix of used and new parts in a used baby AT case with fast 486 with decent RAM, sound and video hardware, CD drive, but a somewhat beaten-up used grayscale monitor until around 1995 -I'd played several multimedia educational games up to that point in B&W . . . including 3D Dinosaur Adventure, where the red/cyan 3D glasses were rendered useless until we upgraded to a color monitor)

Junked: (Actually, I regret junking most of this stuff after I got access to a soldering station)
