Online Repository for Hardware Configurations?

Great_Jehovah asks: "I've done a lot of trial-and-error and spent time researching getting various devices (e.g. motherboards, USB devices, DVD burners) working on Linux. I've also spent a bunch of time configuring different pieces of software for particular applications. I would like a nice centralized place to share these pieces of knowledge and also to see what others have done. I've looked on Google but either I can't conjure the right keywords, or this place just doesn't exist yet. Anyone know where such a site exists? If not, I'll start one."
