This unit has better specs than advertised.  Here's what the unit I got came with:Specs of the unit:- Intel(R) Celeron(R) 2955U @ 1.40GHz- 4GB ram- 64GB SATA disk- 8 Series USB xHCI HC- Wired ethernet: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller- Wifi: Intel Centrino Advanced-N 6205 [Taylor Peak]- Intel i915 graphicsI was able to install Linux on it without any issues.  The network devices have firmware in the Linux kernel firmware repo, so no faffing with compiling drivers off github or anything like that.  All the components worked once the non-free firmware blobs were installed.  I plan to use this as a network appliance so no comment on the graphics, I only used the vga output long enough to get ssh installed.  So far so good on using it headless, all the components seem to be in good shape and well supported.It does come with what appears to be install hardware for a additional SATA disk.  I didn't open it up to see what that install would look like.  This hardware appears to be for adding an additional disk as it booted into Windows out of the box.The two wifi antennas it comes with are a bit puny.  Unfortunatly it uses SMA connectors and not SMA-RP connectors commonly used by wifi devices, so you can't just buy better wifi antennas and connect them up.  Honestly the wifi is the weakest link I've found, but overall still happy with the purchase.
