GizMac has started accepting preorders for the soon to be released 6U XRackPro2 model. The new 6U size server rack will join the current 25U, 12U and 4U XRackPro2 models in the battle to reduce noise from loud equipment. The upcoming 6U model is expected to reduce noise by up to 80%, as with the current XRackPro2 server rack line. The 6U XRackPro2 is priced at US$749.99 and it is expected to be shipping by mid-March.
