Reusing a laptop monitor ends up being a financial wash. You have to purchase a driver board for it, since most have the driver integrated into the motherboard. Often, those driverboards end up costing the same as a more modern and possibly higher quality LCD.
That's a nice RasPi case. My only concern is heat: that's a RasPi Model B with a rev 1.0 PC board. Because of a design oversight corrected in the rev 2.0 PCB, the USB/LAN chip on some of those rev 1.0 boards overheat. In an enclosed case inside a warm PC, you could easily have overheating problems if there's a lot of Ethernet activity.
This only occurs with some rev 1.0 units. You can get heat sinks for the RasPi SoC and USB/LAN chips, which helps.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
