Raspberry Pi is not smaller, but likely to be weaker than the MK802 as a server. Here is the UnixBench result and the perspective.php output running Moodle 1.9.19+ on a Rasperry Pi Model B Rev. 2.0 (512 MB RAM) running Raspbian "Wheezy" 2012-09-18.

Here is an even cheaper ($15) quad-core Single Board Computer with an impressive up-time. 

For a small team, It has proved to be a good option to install, test and learn moodle.

Hi George,

You may be interested in some work that Paul Verrall has beendoing with MooPi.

Also, whilst long uptime is kinda cool, it's also kinda not - it means your box hasn't been patched in 150+ days too ;)

Have fun,

Andrew

In this day and age a long uptime doesn't specifically mean the kernel hasn't been patched. There are number of technologies that allow live kernel patching and loading a new kernel without a full reboot.

Ksplice, kpatch and others come to mind.

However, I agree rebooting occasionally isn't a bad thing.
