Forgot to mention free shipping to US.  Long shipping time granted but still free.

They're flat tops though. :/ Interference with lower profile keycaps + requires a bit of sanding.

The switches I am putting mine in will be getting cut to allow the switch tops to be removed with LEDs installed and to allow the LED to sit lower in the housing.

Interesting. Will look forward to your build log! :)
Will you be sanding two sides of these LEDs so they'll resemble square LEDs? From a quick examination of the bottom switch housing, I'm not sure how much clearance is required before LEDs get in the way of the plate-snapping tab. Will round LEDs fit?

Build log will be posted.  It will come in two parts.  One for initial assembly and another when the LEDs arrive.  The wife really wants this thing up and running so the LEDs will have to wait as I didn't pay extra for quicker shipping.
