Not quite on the same level as yours but here's mine, this weighed in around 10 lbs 9 oz (4.8kg) at a meetup and won me an award for the heaviest board there that day. Most of the case is 7075 aluminum but the bottom half has a big brass weight, and the plate is brass as well.Show Image(https://i.imgur.com/GK625mT.jpg)
What is the name of this kb / case? Thank you!
