I moved last October, from an apartment with utilities to a condo where I have to pay electric. When I was there, the PC was on 24x7 and now it's not. I want to start leaving it on again, because there are a few services I want to start to do.... So, without giving more of my life story - what type of increase should I expect in my electric bill? I know it varies on a lot of variables, but does it make a sizeable impact? Also, not related directly to this topic but still power related, what are the main differences between using a normal molex power adapter vs. a SATA power adapter on a SATA drive?
