Mac Mini Vault, a co-location facility in Wisconsin just north of Chicago, has debuted a customized 48U APC Netshelter cabinet configured to hold up to 140 current-design Mac minis, with the quad-core i7 Mac mini server particularly in mind. The Minis are mounted vertically on specially-designed shelves in a cabinet with six APC switched Power Distribution Units (PDUs) for remote power cycling if necessary, backed up by uninterruptible power supplies and a generator.
