16TB on Small Computer

This is exactly what I need, 16TB of storage space in the size of small form factor computer (and Raid5 to top it off.)

I present you Black Dwarf - a custom-made system with a simple goal: to place as many hard drives - and the computer to run it - in as little space as possible. And the results are truly impressive.

Besides the 8 mais hard drives, it even carries two additional 2.5" drives - which made me think about the possibility to use an SSD as a fast read/write memory cache to make even faster.
Now... if only I had the budget to do it all...
