Simple, Bare-Bones Motherboards?

After my Windows box recently lost its life in a puff of awful smelling smoke, I tracked the fault to the motherboard. Now I'm in the market for a replacement board, but all the boards I find seem to be all-in-one models with on-board everything. I already have a good graphics card, NIC, USB audio device, etc. I just need a no-frills motherboard like I used to be able to buy. It seems like a waste to buy a board with all the built-in stuff (and probably pay extra for it) when I'm never going to use it. Has anyone else had similar experiences? Do a lot of people actually use the on-board stuff? Is it still possible to purchase a motherboard that's *just* a motherboard?
