If you do, grab a cheap mSATA drive (I got a 30GB and use about 1GB of it lol) and hit me up in Trust. I'll send you a brief list of instructions on how to tweak pfSense to add a license file for the Intel NICs and set up the system to use the SSD properly. It only takes a minute once pfSense is installed. It's very simple - four screws, pop off the case lid, slot in mSATA, and boot over a serial null modem (or serial null modem to USB) cable using Putty. I love it.
i see the seller has a few PC Engines APU2C4 devices varying in price (and colour), looking at the description, one says starter kit which i assume doesn't include an OS on it
when you buy either of them do you just need a mSATA drive and away you go?
also how do you get pfsense on there, via usb pen drive?
