I stopped mining, and frankly kind of forgot about bitcoin for almost 2 years, but now that I'm done school I can afford to focus on it again.  My rig just has 2 5830's, so I'm not actually going to be mining much at all.  But my apartment is electrically heated anyways.  So what I'm trying to figure out is the wear and tear on my rig (which I do use as a general purpose PC) worth the very small amount I'll be mining, or should I just stick with 100% my actually electrical heating (my rig won't completely heat my place, but it will help)

Thanks for your thoughts.
