"The Ultra m998 is so named for the exalted m998 HMMWV (better known as the Humvee): a lightweight, high performance, four wheel drive, air transportable & droppable, land mobility system. For comparison: the Ultra's m998 is constructed mainly of lightweight aluminum and plastic parts, sports four optional castors (wheels), a removable motherboard tray, the ability to remove every panel, and also boasts a roomy interior. In concept at least the m998 sounds akin to its name sake's description. Benchmark Reviews however wants to see if Ultra's m998 Aluminum Mid-Tower ATX Case ULT40069 can live up to this legendary reputation, so we've taken this baby for a test drive."
