Thanks for a very nice review. I own four of the original Argon One cases. They are really excellent cases for overclocked Raspberry Pi 4s. I overclock my RPi 4s to 2250 MHz CPU and 750MHz GPU and these are the only cases I have tried that can handle the thermal load under heavy sustained use. The close-up shots of the rear USB 3.0-to-USB 3.0 jumper is intriguing. .A few questions not answered in the article are:
What controller chip is used for the integrated USB 3.0-to-M.2 SATA bridge? E.g. Is it an ASMedia ASM1153e or ASM235 (both of which support TRIM and UASP)?
What disk throughput does the integrated M.2 SSD connector give? Some disk benchmarks using FIO (Flexible I/O Tester) would be helpful. For example I get 395MB/s Read and 332MB/s Write on my Samsung 860 EVO M.2 SSD via a Ugreen M.2-to-USB3.0 enclosure (with ASM1153e chip).
Does the rear USB 3.0-to-USB 3.0 jumper-adapter put out RF interference that would interfere with 2.4GHz WiFi or nearby Bluetooth devices?
What remote controls work with the built-in IR sensor? Will this sensor work with HDMI CEC remotes e.g. our TV remotes? (No info on Argon 40's website.)
Why did Argon 40 block off the micro-SD card slot? It makes no sense to deny access to a working card slot. To swap micro-SD cards, you'd have to unscrew the top of the case, causing wear-and-tear to the thin thermal pads each time.
How noisy (in dB) are the fans when they kick-in? Is the new case's fan larger that the original Argon One's 30mm fan?
