If you think I'm putting any money into this system, you can think again! ;-)
I also can't be arsed to go inside it, those heatsinks are horrible to use!
The thing's not overheating as such, it's just that 1.8GHz is excessive for a computer that starts up, does nothing, then shuts down 9hrs later, most days having achieved nothing (it's an A3 inkjet right next to a colour duplex A4 laser)
At most it'll print a few things and/or install it's windows updates.
