Difference between Mini-ITX and thin Mini-ITX

form-factormini-itxmotherboard

Recently, I've noticed a new type of motherboard form factor: Thin Mini-ITX.

I've tried to find specification of it, but couldn't find any useful info. Wikipedia page about Mini-ITX doesn't have any references to it.

So, what is the difference between old known Mini-ITX and new Thin Mini-ITX? Is there a some new standard behind it or it's just some marketing ploy?

There's an older version of the spec that's available at Intel.com: Thin Mini-ITX spec 1.2. The fundamental differences are:

  1. Z-height restrictions on the I/O shield.
  2. SODIMM instead of traditional UDIMM memory
  3. On-board power-supply adapter, so you use an external brick power supply.
  4. Locked CPU location. Many chassis have custom thermal solutions, so a locked CPU location still enables choice of motherboard.
  5. Zoned I/O ports. This is more difficult to explain but due to the space constraints of an AIO, the wires can't have too much slack. Again, most USB ports, case fans, etc. are only deployed into certain zones to ensure interoperability between any chassis.
  6. LVDS and some eDP support. Enables internal video. If your system has an integrated panel (AIO), you don't have to run a cable out of the board back into the panel.
