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.
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.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
