Easiest way to open indigo to check capacitors

You are right, it looks like you don't need to remove the keybed first - you can leave it on the chassis.

So I'm guessing you just need to unscrew the red ones in order to remove the front panel:-



Failing that, you may need to do the yellow ones (side cheeks) too.

Once the front panel is removed, you will need to unscrew a few screws on the rear of the unit too (where the jacks are), there were around 10 screws on my older Indigo. Not all need to be unscrewed, think I only unscrewed 8 from the rear, your Indigo 2 may be different, use your intuition.
