HP has released their Z1 workstation. All-in-One devices have been a double aged sword, but HP touts the Z1 as the first true all-in-one workstation. With the ability to self service parts, run full Xeon processors, and ECC memory, not to mention the ability to run mirrored 2.5″ drives, the Z1 gives you the full workstation flexibility without the footprint of a tower chassis. A few nice features include USB 3.0, an additional display port for dual monitors, the 27″ glossy monitor, and a locking case. The last is most important if you want to have the flexibility of using the included internal USB port. The idea that you could secure a USB drive internal and then still have portable data of a USB drive.
Below is a small video of the system and how you could open and service the unit.
