Just ordered a 5-pack of these for some mini-mining fun. Don't want to spend the electricity money or deal with the heat of a big miner, so these are perfect to just has away for a few cents a day.
And they arrived already!
3 of them hashing away at 200mhz - truly was plug and play with the recommended build of cgminer. Last 2 are waiting on more usb cables.
Using a 550w PSU I bought for a PC build that didn't happen; and a powered USB hub just to avoid any bottlenecks (Probably not a thing, but whatevs)
The pods are smaller than I expected (about a 4 inch by 4 inch cube) which is nice. You could fit quite a few of these on a shelf/rack. Mine are on a bakers rack so there is airflow below the boards as well.
