 For the most part, the chassis components are cross compatible. The G chassis has mounting provisions for every type of front panel Shuttle used with this series, both screw posts for the G2 faceplates, or snap-in points for the G5 faceplates.
-The only gotcha here is that the front panels have exact port cutouts that may cause problems if you attempt to mix and match front panel components. Pay attention to this as you work. Some of the front panel boards also have different means of connecting to the motherboard (some use the standard headers you'd see in a full size PC, some use a smaller pitch connector, and some use a ribbon cable).
+The front bezel and ports are where things can get...complicated. Shuttle used a number of different styles for wiring up the front, and you need to be careful of this. Thankfully, the USB port board is modular and can be swapped out if need be.
-However, in every case observed so far, the front panel essentials (that is, the power button, reset button, and LEDs) all use the standard front panel header connector that you'd see on a full desktop, and most (if not all) Shuttle motherboards have a standard header on board just in case. So worst case, you can connect the buttons and LEDs directly to the motherboard and potentially forego the front panel USB/FireWire/audio.
+There are three styles I've seen for wiring up the front panel:
-The ribbon cable style also appears to be cross compatible with other boards and front panels that use it. (Observed moving from SS30G2 board to SA76G2 board in the same chassis.)
+  * Standard pin headers, same as full desktop PCs
+  * Combined (but smaller) pin headers, similar to USB 3.0 pin headers, kind of
+  * Ribbon cable between USB board and motherboard (front LEDs and buttons plug into pin header on USB board)
+However, regardless of all this, most (if not all) Shuttle boards have a set of standard pins on the motherboard for USB + buttons and LEDs. So at worst you'll still get USB and front button/LED functionality. Just maybe not FireWire (or TOSLink if you have a Shuttle with it on the front).
+Given the USB board is modular, I highly recommend just keeping the USB board paired with its respective motherboard to make things less complicated.
