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.
