I have a board for sale is almost new I just used for couple of hours to test the power consumption and for me is to much from 13.8W to 17W max. I needed a lower power consumption the performance was not important for me so I purchased this Link
I sell this for only 89$ US or CAD but you need to pay also the shipping about 15$ for Canada and US. I prefer PayPal for payment.
Included is as you can see in the photos the board + 512MB RAM (you can upgrade to max 2GB) ,backplate ,two SATA cables and one IDE cable also I include a PCI 4x video in card to use for video surveillance you can see the last photo it works great in Linux I used with motion.
This board is made by BCM is the MX945GSE and is designed for industrial application you also have dual gigabit LAN. This is the V1 so only 2 serial ports as you can see in the photos.
Link to spec
PS: I can also provide you with ATX power supply at extra cost see the link in my signature.
