We're not in the habit of following the ITX chassis market that closely, but Gigabyte has recently introduced a rather interesting product. The MIB T5140 is an ITX chassis with a twist, it doubles as a monitor stand.
Space is at a premium in most offices, and that's where compact all-in-one PCs and nettops come into play. Gigabyte's new case will basically allow you to build your own nettop-all-in-one hybrid of sorts. You can use it with 19- to 23-inch panels weighing up to 5kg, provided they have 10x10cm or 7.5x7.5cm VESA brackets at the back. The upside is that you'll be able to adjust the height, something you can't do with most cheap panels you would usually use for with a nettop.
The chassis measures 250x65x445mm, has a 65W PSU and features standard size 5.25-inch external and 3.5-inch internal drive bays, so you won't have to splash out more cash for slim optical drives or 2.5-inch HDDs. Speaking of economics, the whole contraption costs just €52, which is pretty cheap for an ITX chassis.
It might not be as aesthetically pleasing as your average all-in-one, but it's still a very interesting proposition for small businesses or home users who could use old, cannibalized hardware with it.
