I will buy old gpu's, and use them to heat my house =D
It's cold and rainy where I live, and heating is useful everywhere!
I figure 10 kwh through video cards is better returns than 10 kwh through heaters =/

Ah, yes and no.

Heaters will probably give you more efficient conversion of power to heat compared to the cards, but it might be close.

For converting electrical energy to heat, almost any device is effective because it's basically the "waste" that's heat. Gas -> heat is still more cost-effective though.

It is more cost effective to use GPUs as a heat source if your house does not have gas infrastructure. A 10kW electric furnace produces the same amount of heat equivalent to 10 kW of GPUs.

You can just pipe all the heat produced into the fan that can distribute heat to the vents of your house.
