So let me start by saying: no good hardware was sacrificed in this project. Only boards that test bad or have no other value.

I've started buying bulk boards from eBay that are listed as scrap. I kinda like the hunt and anticipation of it. Sellers can't really take great pictures when there are 40+ lbs of motherboards and etc. so if I see something that looks interesting, I'll bid and see what happens.

I've gotten a few working SS7 boards along with some fun video cards: Diamond Stealth S220 (Rendition V2100), GeForce 4600 Ti, TNT2 Pro/Ultra, some decent Intel ISA NICs, etc.

There are some that need repair (blown caps, etc.) that will end up in working order.

But I've also ended up with a ton of crap and non-working stuff. PCI Modems, Dell socket 775 boards with mangled socket pins, video cards with seized fans (and dead GPUs), etc.

One of my co workers showed me a picture of a clip board made from a motherboard PCB with all the components removed. Similar to: board10.jpg

I thought this was a pretty cool idea so I started with some of the boards I have:s0H1pC2.jpg?1

Now, I don't know if you've ever tired to do something like this, but let me tell you, even with heat guns and reflow equipment it takes a long time. I gave up on the board and did a PCI win modem instead, that still took a while. Surface mounted components came off easily, even the socket 775 which I was surprised. DIMM slots, bus slots, anything soldered through the board requires time and patience and a lot of cleanup. I'll revisit it another time when I've perfected my technique a bit.

Once I had the north and south bridges off I was sort of just looking at them and had an idea:

I couple of power tools later:

And then I threw it on this:

Now I was on a roll, and the next reuse item was a GeForce 2MX with a heatsink that had thermal glue on it 🙁 It took a while to soften and clean it all off:

I also had a dead FX5200 and Radeon 9000. Tiny little heatsinks with fans that gave up spinning a long time ago:

By this point the Intel southbridge had already been in my pocket for a day a quite scratched up so these got a polyurethane treatment front and back, it remains to be seen if it will last long term. I've also got a bit better with the high speed drilling:

I showed my wife and was super excited, her not so much. She did surprise me a couple of days later with some jeweler items to make actual proper keychains and I must say I'm quite impressed with the results so far:

QFP and PLCC mounting also can produce some cool items once the sharp pins are ground off:

I think I may end up selling some on the side on eBay or such. Got a favorite GPU or chipset you want made into a keychain? We don't want to leave the ladies out so I've also got ideas for earrings perhaps?

Thanks for looking, I think I've found my winter projects. It's perfect to keep me busy and also keeping otherwise vintage or old chips out of the landfill. Plus as I get older I've found I want to keep 'junk' less and less. Now I can keep just a chip or two instead of the whole dead board.

Great idea! May I also add refrigerator magnets to your list of DIY dead pc parts projects? Old chipset heatsinks, ram, cpu's, etc look great on the fridge 😀

Main pc: Asus ROG 17. R9 5900HX, RTX 3070m, 16gb ddr4 3200, 1tb NVME.
Retro PC: Soyo P4S Dragon, 3gb ddr 266, 120gb Maxtor, Geforce Fx 5950 Ultra, SB Live! 5.1

Thanks! That's a great idea, I hadn't even considered that.

I like the slightly-glossy look that the polyurethane coating provides.

I would second the fridge magnet idea. Also, Christmas ornaments might be a thing in ~2 months.

Fun times. I've been thinking about doing something similar once I finish going through everything I have.

Take a look at Etsy to see what kind of stuff people make out of old electronics.

I'm not sure how that poly coating will hold up. A lot of the stuff I see on Etsy is encased in some sort of resin.

For that motherboard - if people put boards in toaster ovens to reflow cracked solder joints, couldn't you put a motherboard in one upside down so all the components just sort of fall off?

I was going to say that too. Not everything will come off, but if you can take the heat you can pull them off after the board has been in the oven.

as fir the keychains, take a small drum sander to the bottom to remove the top layer of the PCB, it will show the copper layer underneath. I may have a few cpu keychains that I did this way around. I'll post a photo if I can find one.
