I have been buying the decommissioned Neoware CA22 on eBay for $20-30 or so. These have a PC compatable, P680 main board with x686 Via CPU running at 1 GHz, up to 1 GB of ram and up to a 1 GB Flash Drive installed as a CF-HD. PCI 32 bit slot but it either needs a right angle adapter or using Universal PCI card with profile no more than 1.3" tall. These units burn about 14-18 watts per hour, have no fan. Standard I/O ports as you'd find on a PC. Good little "appliance" platform for TC and your bevy of extensions/scripts to do what you described. After loading quite a few extensions I was still only using 150MB of the flash drive. And, of course, RAM was hardly being used. If you are interested in a site which deals with thin clients and repurposing, search for "Thin Clients Parky-Towers". He's done a lot of research and implimentation using these boxes.
