Even the plastic back plates are missing? ?

Yeah! PCBs only. And some are missing some resistors from where it looks like someone levered the heatsink with a screwdriver 🙁

the only interesting cpu's are first and the last one, they're coppermines.

all other most likely a regular katmai/deshutes + 2 Klamath. check cpu's and if not 600 katmai or 400 unlocked deshutes, then just give it back to e-waste.

Slot 1 coolers are sold on the "fleabay"-dot-com. Another option is to make your own 3d printed brackets/adapters for regular s.370 coolers.

The problem is that they're all depending on the plastic backplate of the Slot CPUs. But I guess that something appropriate could be 3D-printed for that function ...

Yes, there's always an option of something to be adapted or 3D-printed. But some models manufactured by 3rd-parties are equipped with their own retention bracket.

The main problem is with prices on the fleabay.

Missing Slot 1 heatsinks and plastic backplates are not a problem. You could buy a few Socket 370 heatsinks (must be large enough) then use a pillar drill to drill 6 holes - 4 for bolting it to the PCB and 2 for attaching a fan. Alternatively you could buy original slot1 heatsinks and modify them the same way.

That type of aftermarket cooler also needs the plastic backplate because the distance from fastening clip to PCB is wrong without it -plus- you cannot have bare metal touching the rearside of the pcb.

I don't know what this Cooler Master cooler kit includes. For the price that's announced it would be shame not to include some piece of thin plastic insulator, plastic washers, etc. parts needed for adequate attachment. The picture was just to illustrate the possibility to attach the cooler to processor's PCB without the original plastic housing of the processor.

Exactly my point 😀

Probably not - as it is designed for mounting on a CPU that has its original back side still mounted.

Ok, picking 3rd-party cooler by pictures is going to be tough.

There are stock and aftermarket coolers for slot 1 (SEPP) celerons that mount directly on the PCB by their own insulated back-plate/bracket. These may be suitable if their mounting holes match those on the PII/PIII PCBs.

Plastic backplate is unnecessary. You can bolt the heatsink directly to the PCB through holes drilled through the heatsink. You will need tiny plastic washers. You can pick 3rd party cooler by dimensions.

It's easiest to just buy one PIII heatsink.

The orientation of those holes is different between Celeron and PII/PIII

I modified a cheap AliExpress universal Zalman style VGA heatsink that I had already. Holes in the HSF already align with two of the mounting holes.

Sanded off the bottom edge of the cooler baseplate for a better fit. Insulated the underside of the heatsink except the core contact area with kapton tape and then a plastic shim that I made.

I'm very happy with the result, seems to cool very well and looks great too!

Boss move! Very nice!
