i really wonder how they are housing the desktop grade hardware. im so used to rack and stack servers (1U/2U), but do you really need that big of a chassis for a desktop cpu, a couple ram dimm's and some ssd? what are you're thoughts?
They have ATX cases on shelves. You can take a look at this tour of their datacenter [1] for more insight. ATX cases are visible around the 3 minute mark.
