I'm doing something similar but totally different
I have an old lap top I am going to use in the kitchen to display pictures and stuff but I also want the ability to look up / write / download recipe's. At the present the Laptop has sufficent space memory and power for doing so. This project you took on was really a lot more involved then the one I am doing as the laptop will still be together even though I have though about framing it and using a wireless keyboard and mouse. However with the kitchen the way it is the only places to hang it would leave it way to high or to low. I am open to ideas though. I'm not a Great carpenter so probably shouldn't try to build anything complex. My wife is the main one who will be using it even though I will use it from time to time. Of course I'll be the one maintaining it. I will be using Fedora 16 or 17 with Gourmet Recipe Manager and probably just use the screen saver for showing pictures.
