Quick intro: NAS drives can essentially be accessed over your local network or worldwide through internet without even having your PC turned on... so, media streaming, file sharing across home is sorted for good.
I was recently looking for NAS solutions, found many enclosures ranging from 25 to 300 (Drobo)... But this one is different because you can turn any USB drive (Thumbdrive, or external) into NAS drive. Brilliant.

I thought this was a wonderful kit, you can connect up to 4 USB drives... It has some extra features, like printer sharing, Bit torrent built in, etc... but I hear they don't operate as swiftly as you would like...
This post is more of a awesome product find than a great deal, but its also the best deal I could find for it... may be not the cheapest it ever retailed for..
