Sonnet’s New Rack Mount for the 2013 Mac Pro ⇥ arstechnica.com

Sonnet’s mount requires only 4U of space; for comparison, rack mounting the old Power Mac G5/Mac Pro required 7U of space. While this rack mount is ridiculously heavy and big compared to the Mac Pro itself, it’s got three PCI Express slots and — hilariously — space for a tape backup.
