Why's it stupid?

It's basically a refrigerator module for your computer and has all the downsides that follow. It's a power hog and has condensation risks that are potentially lethal to your comp's components and even yourself if it shorts out the PSU to the case. It has a single refrigerant compressor that has a pretty serious current draw upon starting and has an electric motor in it, which means it's not truly fanless.
If it springs a leak on the piping, your room is now full of aerosolized compressor oil and R-134a refrigerant while your computer overheats. It's just bad all around unless you're running a literal supercomputer. This unit might do something different, but the only other phase-change cooling method I know of requires a fan and a replenishable water source that also raises the humidity of your room over time.
Correction: This looks like it uses a glorified heatpipe system, which has an upper limit of cooling capacity before needing bigger or more pipes. It can also eventually reach a saturation of heat and stop cooling effectively if it gets put in an area with low airflow. This thing is also HUGE and very expensive for what it is. Heatpipes are basically copper tubes with a little cotton rope in them soaked in water that's closed at both ends. $800-900* does not justify $20 worth of aluminum fins and $30 of heat pipes. I spent about $200 on the case and Noctua casefans that I use on my comp and it's so quiet that I barely hear it. I went overkill on the fans, so it could be even quieter. *It's actually much worse in price than I thought!
