Most normal people are happy for their PC to remain the heavy beige box that sits in the corner under their desk.

But then there are people like me - I'm a gamer and a network engineer - My life revolves around PC's and I lug quite a few around each day - Either to carry a dead base unit back to my pit, or to take one of my rigs round one of my mate's houses so I can annihilate him at Q3 without him moaning about lag - But that often takes two people two trips, and I often drop half my tools whilst trying to ballance them on top of a doomed PC.
