Features and Specifications

Don’t let the name fool you.  Ultra’s m998 mid-tower case is much more than a utilitarian enclosure.  It may be named after the rugged and versatile M998 HMMWV (Humvee) military vehicles but it features a wealth of useful features.  Ultra designed the m998 mid-tower ATX enclosure for PC enthusiasts planning to build the ultimate gaming, multimedia, or high-end workstation system.  Inside the oversized, aluminum enclosure you will find two 120mm cooling fans, 11 drive bays, a removable motherboard tray and Ultra’s unique Power Bar system.  The m998 also comes with a large side window, removable top and side panels, and caster style feet.

Ultra m998 Specifications (from Ultra’s website)


The Ultra m998 mid-tower enclosure ships wrapped in plastic and nestled between large Styrofoam end caps inside a bright orange and black retail box.
