While they have Windows XP loaded, we were booting them to a Linux OS from a USB adapter. Will run dual widescreens with no trouble.

I've never tried to install this OS to the onboard flash but it should be possible for an enthusiast. Being fanless these would make a nice NAS when coupled with an external hard drive, or a media centre or HTPC when used with a DisplayPort to HDMI adapter.

Do your own homework but you can add RAM to these and they have a spare SATA port on the motherboard for an entheusiast to tinker.
