Open source router firmware project OpenWrt ships its own entirely repairable hardware
(www.theregister.com)
This is a most excellent place for technology news and articles.
I also wanted to chime in with the perennial point that while this device is a pure expression of the OpenWrt project, they also support hundreds of other devices including, amazingly, a number of large switches, so if you wanted to ditch the separate route appliance altogether you could get all the features with only switch hardware.
