Back fan pulling warm air out of the case,

Front fan pulling cool air in to the case.


so if anyone could give me some pointers there, I'd appreciate it)

I'm leaning toward the PSU now - the fact that the computer 'lasts' longer if the system's unplugged proportionately long almost gives it away, right?

That does sound logical. What I would do is the fan and cooling thing and if you are still having problems, then go for the PSU. Just remember, I mentioned that early on, so could very well be it. Another one of those however situations, if unplugged longer, cools more also, so take one step at a time IMHO.
