A lightweight Tray with mounting pillars for an ITX motherboard. There are no holes pre-set. best to place the motherboard on top of the pillars, mark the holes and drill through with a 2mm bit or similar for motherboard mounting screws. The plastic will not last more than a couple of screw/unscrews so for maximum versatility, once you have drilled the holes (straight) flip the tray over and get some matching nuts to some longer screws and use a soldering iron to melt them into the plastic. then enjoy your robust motherboard tray!used a 20% fill. will require drilling out. Don't forget to make it more robust by using longer screws, and melting a nut into the underside with a soldering iron.
