Well,I get my boards from a "bazar"(or a fair to say so,where you get various things you need)and generally I pick what I can find in good shape.So far,from 2012 until now here's the list of what I remember I bought:
1.Luckytech P5MVP3
2.KOB KLE133 FSMX (was some kind of PChips M810 or such but without an AGP slot and the onboard video was damaged,so I was using a PCI video card)
3.ECS K7VZA
4.EFA Socket 7 board (VIA chipset,was running a K5 100 w/ 48MB RAM)
5.Lucky Star 5MMVP4
6.FIC PAG-2130
7.ECS K7VZA relabeled as Matsonic 8127C+
8.ASUS P4B533-V that was dead,saved the cooler and I think the CPU too.
9.ASUS A7V8X-X that was dead too
10.EPoX EP-4PLA3I with bulged caps
11.Chaintech MPM800,which I used until now,hope I can solder the BIOS onboard someday,yet I suspect I accidentally erased the BIOS,which in case I need another motherboard that uses a KT333,KT4oo or anyting like that to reflash,that doesn't have a soldered flashchip.
Now I should see what I can find,and if I have CPUs.Last time I had to get a PS1,as the only board available was a S939 Gigabyte,and I don't have any 939 CPU.
