When you build a new PC, you have to try all your components BEFORE putting everything in your tower case.
Doing so, you often find yourself wondering where am'i going to lay my motherboard? i don't want shortcircuit or anything damaging my mother board...
Wonder no longer, here is the Motherboard testing legs. It's plastic so it's insulated. It's really stable and you'll have plenty of air circulating around to cool everything down.
