The U3 is a small case from Cooltek and it has been made from aluminum entirely. It allows the installation of mATX as well as miniITX motherboards in combination with ATX power supplies. In addition there is enough space in order to create a small HTPC, file server or even a small gaming system with “mini” cards.
Today we’re having a look at another mini tower case, which in this case goes by the name Cooltek U3. Apparently the U3 is most suitable for office PCs, HTPCs, media servers as well as mid-range gaming systems.
