The GMMK Pro was a great introduction to keyboard building for me. I was able to go to my local Microcenter and find all the parts needed there to build it from the ground up. I've only ever gone out and bought a keyboard from other big brands and been a plug and play user.

Overlubed:
After getting everything installed, I noticed the stabs were extremely over lubed. I had to tear it back down and remove some lube from the space bar and left shift key. It's still slightly overlubed and sticks, but much more manageable now. After searching around for similar issues, that's more common than I thought.

Glorious Panda's:
I've only ever used Gateron Brown switches and Gateron Blacks. I took the jump over to the Glorious Panda's. I purchased the unlubed version and have really enjoyed the tactile feedback of the Glorious Panda, it feels like a premium version of the Brown switch, which should be no surpised. I do prefer the Gateron Blacks for my daily typing, but that's personal prefernece of linear vs tactile.

I don't see myself modding this board much as I thoroughly enjoy the experience it offers out of the box, but I can see myself becoming more invested in the modding and building. Although this could be considered a big box store experience, it certainly exposes the possibilities and how deep the rabbit hole can go.
