The ECS LIVA is currently on sale at NewEgg for $165 after instant rebate and you can knock another $33 of that price until August 31st with the code LIVADISC.
This tiny little machine contains a Bay Trail-M N2807 @ 1.58GHz, 2GB of DDR3L and 32GB eMMC storage with 802.11a/b/g/n and Bluetooth 4.0 thanks to the NGFF card installed in the M.2 slot. As you can see below it has both HDMI and D-Sub ports which can be used simultaneously and has onboard stereo audio thanks to the Realtek ALC282. It only draws 15W and is completely fanless, making it a perfect HTPC. You can get the full specs from ECS here.
