Here's a cool little Linux client which costs less than US$100. They are low power and would make a nice little server or monitoring box for applications. I need to replace some DNS servers with these.

Bangkok-based Norhtec has unveiled a sub-$85 mini-PC claimed to be the most affordable Linux thin client system to date. The "ultra-low-power" MicroClient JrSX is based on a 300MHz x86-compatible SoC (system-on-chip) and includes both CompactFlash and 2.5-inch hard drive storage options, along with 10/100Mbps Ethernet networking.
