 We recommend running Arch Linux ARM on the Raspberry Pi due to it being a simple lightweight linux distro that boots in around 10-20 seconds. We used Nginx with php-fpm as we found early on that Apache2 isn't particulary stable on the Raspberry Pi and consumes a large amount of resources when compared to Nginx.

+Hardware Compatibility
+======================

+It's worth noting that our initial prototype kept causing kernal panics when we tried to write to the memory sticks. We narrowed this down to the TeckNet USB 3.0 10-port hub we had purchased not being compatible with the Raspberry Pi, whether this is because of it being a USB 3.0 hub (the RPi is USB 2.0), or more likely power issues backfeeding into the RPi, we decided to obtain a new hub based on the list confirmed to work with the RPi found at http://elinux.org/RPi_Powered_USB_Hubs.
