@Ryan780 I have 2 fanless machines, running W7 pro, with SSD, on 12VDC. One with dual lan, VGA, HDMI, rs-232 (some changeable for rs-485). No heat, no noise, low power (15-25w average for intel i7), no moving parts. Can run Linux also. Highly recommended !
*Edit: I have also an old ELO touchscreen and it works with both (with the W7 drivers downloaded from their site)
