These t820 thin clients can be converted to whatever you like by adding a proper hard drive either in the mSATA slot, or in the 2.5" slot right above it.  The drive caddy for a 2.5" SATA drive is present, but the wacky screws with the blue rubber oversized washer HP uses are not (they are sold here on ebay).

For upgrading the memory, these small PC desktops take (laptop ram) SODIMM DDR3 12800 low voltage RAM.  A 4gb stick of RAM is installed into one of the slots.

We will leave the 16gb mSATA drive installed. Chrome OS? Linux?

HP Original 130 watt AC adapter included.

We will warranty the hardware for 30 days.
