Small-form factor PCs are coming out these days and the Stinger 553 desktop is a clear example of how these things look. Obviously meant to save on space from the traditional CPU ATX tower casings, the Stinger is something that anyone would want in place of them.
As far as internal components are concerned, the stinger has a list of features that many may find familiar. This includes:
8x USB 2.0 ports
2x RS-232 Serial Ports
PCI Express and USB interfaces
No word on price, but mil spec anything is rarely cheap, there is an SSD and an aluminum alloy chassis to make matters even more expensive. However, for your money you are getting a tiny computer that will work under almost any conditions that can be thrust upon it without making a sound as there are no moving parts. I want one, badly, this has XP Ninja Mk II written all over it.
Certainly this type of small-form factor PC cases provide us a glimpse of the future. This is certainly something many would really find worthy to have soon.
