Thank you. All very useful to know. Hadn't thought about the weight like that - but hopefully a smaller case, although just as heavy, would be less awkward to pick up and hold/carry?
With the processor heat, are you saying that one of the higher-spec fans would be a safer bet?
My wife needs a PC for photo and video editing. She'll be moving it around the house often (from the loft down two flights of stairs and up again), but with monitors in both locations already. No need to be as portable (and therefore restricted) as a big laptop, but a full desktop would be too...
