Even came with keycaps. Maybe I missed it in the description, but I didn't think I was getting any and yet they sent them. I did order the key switches with it... maybe they came as a set. I watched the video, and built it in an evening with no problems at all. Now I'm going to print out a case for it. Thanks!
Edit - even came with the LIR2032 rechargeable battery. I was able to cancel the Amazon order for 4 (1/3 the price of 1 locally). Thanks!
