content: From what remained of my upgrades to a laptop, I have now a few spare processors:Intel Core Duo T2300E (1.66GHz dual-core x86)Intel Core 2 Duo T5600 (2.16GHz dual-core amd64)The supporting chips from Intel, Intel 945PM memory controller and Intel 82801GBM (ICH7BM) or 82801GR (ICH7R) can be bought cheaply too online, but I cannot find anyone selling a ready-made motherboard built with these. So what can I do with them? Is it a good idea to experiment with building a PC motherboard here?

content: You can find laptop schematics online if you want an idea of how many (hundreds) other parts you'll need to get a working motherboard. You are unlikely to succeed if you don't have experience laying out many-layer boards with both high-power circuitry (the CPU power supplies are buck converters with tens of A outputs) and high-speed digital signals. You'll also need firmware of some sort...AFAIK the newest PC clone anyone has built as a hobby was a 386:http://www.s100computers.com/My%20System%20Pages/80386%20Board/80386%20CPU%20Board.htm

content: It seems to be a sad fact of x86 PCs that perfectly lovely socketed CPU chips essentially become useless as soon as matching motherboards are no longer "available." :-(You're more likely to be be able to find a complete used system of the same vintage for less than a motherboard...(heh. I recently "repaired" by daughter's laptop using a fan/heatsink module and power connector purchased from eBay, and relatively reasonable prices, and then realized that I might have been able to go to someplace like "Weird Stuff Warehouse" and bought a relatively complete (but not working) laptop, to harvest for similar parts, for about the same price. Sad.)

content: The old '486 and pentium era chips made good beard combs! Nowadays they are too small and don't even have pins.Others here are right, those CPUs are being scrapped by the thousands and are essentially worthless.As for the idea of building a motherboard ...
