Everex gPC Mini, The Perfect Mythtv Box?

I found this hardware today on Digg.com and I immediately thought of a Mythtv frontend. This has the power to be a frontend and backend but hard drive space would be the limiting factor there. USB hard drives would be fine for this form factor and they do work with Mythtv. This mini pc will be very efficient and help offset some of it's cost by energy conservation. I know the full desktop that I currently use for Mythtv takes up much more power than this pc. My budget does not allow the 500 dollar price tag, but it will be interesting when the price on this hardware eventually falls. The Everex Cloudbook laptop is priced around 400 dollars but does not have the higher end specs that this gPC does.

Most sources I have read say that Newegg will be selling the gPC on March 1st but I have not seen it as of today the 3rd.
