I haven't seen that one, looks nice but no option for the fan.
A lot of these "metal cases that act as heat sinks" don't really do all that much. Especially if you use the thermal compound included and not real thermal paste.
It seems the later firmware does a good job reducing the thermal problems with the Pi 4. I am going to do some testing when I get my Pi 4's in, I am still using Pi 3's and Zeros. I'm still going to go with a fan case and can run the fan in quiet mode if cooling isn't a big concern (there are two pins you can choose from when attaching a fan to decide if it is in quiet mode or full-speed mode).
