The Raspberry Pi is a pretty neat little computing unit. Plenty of geeks are doing all kinds of neat things. Just a couple of days ago, we heard about the DukePad which happens to be a DIY tablet powered by Raspberry Pi. Need an easy way to hold 2 or more Raspberry Pi units at your place? The stackable Setek Dual Raspberry Pi Case can help. It has a rugged design and holds 2 units. What’s neat is you can expand the case to hold even more units. This is a super handy case for those of you who experiment with multiple Raspberry Pi units all the time.
