The Lian-Li PC-TU300 is a PC case with a unique focus: mobility. This is achieved not purely through low weight or tiny dimensions, but through the inclusion of a carry handle and an optional screw-in trolley system. Once installed, the TU300 becomes quite literally carry-on luggage, small enough to fit in an overhead locker and nimble enough to roll around the airport without breaking a sweat. It’s an intriguing concept, so let’s see how well it works!
