so, are you saying that all devices that use the same amount of energy are equally efficient at heating space? Clearly this is not true - while electric heaters are all considered "100% efficient", in that there is no loss of energy, different electric space heaters, for example, heat with varying degrees of efficiency per watt of electricity. And putting your space heater in a box and facing the wall will heat your home less efficiently than using it properly.
So yes, the energy consumed by the computer will create heat, but it is not *solely* the low wattage that prevents any appreciable heating (although I admit that is the most important factor).
Just being pedantic - sorry.

How efficient a house is heated depends on how much and how the air moves around in the house and where the heater is placed.
All electrical energy that a device uses is transformed into heat+potential energy+light. A computer with the screen turned off only produces heat.
So if you place your compter in a "good" spot, like I have (for a different reason though), under a window it will heat my home as efficently as any heater can. Not as much but as efficient.
Ofcourse it wouldn't be practical to rely on you computer, TV, VCR etc to keep your house warm but no one said that eather.
It might seem starnge that a computer, or a vacuumcleaner for that matter, is as efficient as normal heater at heating air, but they are
