Just a small tip for the Arduino software.
In a system like this I would've implemented the WDT (Watch Dog Timer) for the safety of your build.
If you don't know what the WDT is, it is a timer within the MCU that need too be reset every X seconds, milliseconds or the MCU will reset no matter what it does. So if the software hangs the coffe maker could run for hours without you know it... which could start a fire in such confined space.
So if the WDT isn't reset the system will reboot and the relays will turn of.
Sheers from Sweden!

Awesome build! Some people have mentioned the fact that moisture could go to the computer parts, but, since your airflow is from top/back to the front, all the moisture will go to the front of the case which doesn't have any electronics (only the fans). The only thing I would do differently is add a weight sensor to the cup holder to stop the water dosing. I think it would be a more consistent way to have the same amount of coffee due to the fact that the water heating time can vary depending on the ambient temperature.
