I will try to help you find a 75% keyboard with your configurations! It's very trendy and popular all around the world. I did have a similar keyboard, but there are so many options available. And you do have to choose the best one according to what you want.
For an acrylic/frosted/clear-ish case, you can check what the best options are there and select one out of them like there are so many Chinese ones.
Apart from acrylic and frosted, the universe has many other luxurious options available for you.
