Hands-On Review: GemPro Enclosure for Raspberry Pi

A reminder for anyone using the RPi 4, the single greatest determinant of how much your board will heat up is... whether or not you're still on the original release firmware. There was an update that was tremendously effective in cooling things off (without damaging performance).
This stinks of blogspam to try sell their new overpriced case.
Not to mention, like you said, with the recent updates that have made incredible progress in dropping the temps, any generic cheap passive case is fine even for quite heavy use. I have multiple Pi's (3s and 4s) running 24/7 and a few doing quite heavy loads (transcoding, etc) all with cheap Aluminium passive cases and have had zero issues since the firmware updates.
I tested on those, but not for performance, just for temperature under max CPU load. I remember getting the impression that a Pi 4 working under that kind of load, and throttling pretty constantly, would probably suffer roughly a 15% performance degradation but I didn't test that assumption much.
I had a funny moment during testing of comparing an 8GB and 4GB Pi 4, each with different revisions of the firmware, and wondering how the hell the temperatures could be so different.
A better test would be to see how far you can get from the access point before degradation of bandwidth kicks in with and without the case.
All they managed to test was that however degraded the signal was, it didn't reach "lost packet" level for their unspecified range to access point.
From experience, I've used a heatsink-looking case on a pi 4 which reduced its WiFi range below 30 feet in some orientations, so it would be nice to see a big more rigor here.

The coolest thing about it is it moves all the input/outputs to the rear of the case.
They shouldn't have been. I have the Argon 40 case for an RPi4. I've overclocked the core to 2.0GHz, and with 100% passive cooling, no fan, it does not thermal throttle at all. I've pegged it at 100% CPU use for an hour with no throttling. The chip runs hot, but it's not a top of the line CPU that needs active cooling. A good sized chunk of metal will cool it just fine.
