MapReduce/Cloud infrastructures built out of cheap NAS box?

Hi everyone,

Do you know any resource about cloud storage or computing made out of cheap NAS servers like qnap/synology ? I'm thinking about that due to the low price of these boxes. Myself, I have a small QNAP and even if the ram is low and the processor also, I thought that having like 10 of these boxes would be great to experiment stuffs like hadoop or distributed cheap web hosting.

(Look at the prices, you can get a 1.2Ghz for like $150. That makes 10 nas for $1500)

Did anyone here try something like that ?
