for system unit
From The Free On-line Dictionary of Computing (18 March 2015) :
The main body of a computer, consisting of a
plastic or metal enclosure, the motherboard, and (typically)
internal disk drives, a power supply, cooling fans, and
whatever circuit boards plugged into the mother board, such as
a video card.
The system unit is occasionally referred to as the CPU,
though this really means central processing unit.
