The size at first surprised me but I could have found that out on the Web Site. It is too big to put on the Desk so I was concerned that under the Desk the Wireless Accessories would not work - No worries there - everything is fine. It is quieter than I envisaged - only when there is no other sounds around can just about hear a faint hum. Everyones build is different and I am pleased with mine. Funds permitting I might have preferred a Fanless Computer but the speed and general performance is very pleasing. Delivery and regular contact about shipping was fine.
