The OpenWrt is pretty straightforward; I've got a document that gives pretty good detail on how to build it. Between the router and a USB memory stick, you're looking at about $120 bucks . John Novack has been blazing the trail with the thin clients;
And a thin trail it is! My time lately, between deaths in the family,
foster dog and now a dead financial machine, I haven't progressed much,
other than to determine it can be made to work.
Thin client pricing on eBay is all over the place, as are the Cisco
3810's and the suitable OpenWrt router.
There is NO free lunch
Thin Client, USB memory stick and a Cisco 3810 do make a nice package,
though, but unfortunately violates the no fan rule!
The BEST thin client solution is the HP 5000 series, but you will need
one with 64 Meg of flash, or be skilled enough to replace the smaller
flash with something large enough to hold AstLinux. Not me!
Or simply boot and use the USB 1/2 gig memory stick for everything.
Your interest will grow beyond this solution long before you wear out
that stick.
