Fortunately there is a lot more good news than bad. Moreover, I have workarounds for <em>most<\/em> of the annoyments and I suspect almost all of these will resolve themselves over time, once the ARM64 Raspberry Pi OS for \u03c04 becomes mainstream. Therefore I&#8217;ll start with the good because TBH I&#8217;m really rather pleased with this&#8230;<\/p>\n<ul>\n<li>ARM64 Raspberry Pi OS works on \u03c04 8GB, almost perfectly, even though it is currently in beta. For reference this is basically Debian Buster compiled for ARM64. It seems much faster and more stable than Ubuntu 20.04.1 LTS<\/li>\n<li>It boots perfectly (and incredibly quickly) from&nbsp; the 1TB Intel 665p NVMe SSD, mounted in a tiny all aluminium SSK USB 3.1 case. There is currently no MicroSD card in the machine at all.<\/li>\n<li>All 8GB of RAM can be accessed.<\/li>\n<li>Zoneminder works pretty well on this OS, albeit with some rather irritating caveats.<\/li>\n<li>System consumes between about 5 and 8 watts of power. I measured this with a USB mini-multimeter. I am particularly pleased with <em>this<\/em> result.<\/li>\n<li>Placing the \u03c04 in the FLIRC case worked out well. After prolonged usage its case temperature ranges between about 33\u00b0C and 37\u00b0C. Placing it on that metal mini rack I built helps too I think. No additional mechanical cooling seems necessary.<\/li>\n<li>The SSK case containing the 1TB NVME SSD is also cool to the touch. I attribute this at least in part to its being laid flat on the metal shelf, just like the \u03c04<\/li>\n<\/ul>\n<h2>A few snaps from the project&#8230;<\/h2>\n<figure style=\"width: 900px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201125-p2410085-raspi4.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201125-p2410085-raspi4.jpg\" alt=\"20201125-p2410085-raspi4\" width=\"900\" height=\"1538\"><\/a><figcaption class=\"wp-caption-text\">Putting the \u03c04 in its FLIRC aluminium case.<\/figcaption><\/figure>\n<figure style=\"width: 900px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201126-p2410119-modem-rack.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201126-p2410119-modem-rack.jpg\" alt=\"\u03c04 on the modem rack (bottom shelf).\" width=\"900\" height=\"2048\"><\/a><figcaption class=\"wp-caption-text\">\u03c04 on the modem rack (bottom shelf).<\/figcaption><\/figure>\n<figure style=\"width: 900px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201126-p2410122-modem-rack-closeup.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201126-p2410122-modem-rack-closeup.jpg\" alt=\"\u03c04 on the modem rack (bottom shelf close-up)\" width=\"900\" height=\"1538\"><\/a><figcaption class=\"wp-caption-text\">\u03c04 on the modem rack (bottom shelf close-up)<\/figcaption><\/figure>\n<figure style=\"width: 900px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201127-P2410134-modem-rack-voltmeter.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201127-P2410134-modem-rack-voltmeter.jpg\" alt=\"Voltage measurement, connected to output of 12 volt to 5 volt buck converter mentioned in an earlier post (reads 5.12 volts)\" width=\"900\" height=\"1538\"><\/a><figcaption class=\"wp-caption-text\">Voltage measurement, connected to output of 12 volt to 5 volt buck converter mentioned in an earlier post (reads 5.12 volts)<\/figcaption><\/figure>\n<figure style=\"width: 900px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201127-p410139-modem-rack-ammeter.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201127-p410139-modem-rack-ammeter.jpg\" alt=\"Current measurement under fairly minimal load, connected between buck converter and \u03c04, booted with Zoneminder running (reads 1.02 amps)\" width=\"900\" height=\"1538\"><\/a><figcaption class=\"wp-caption-text\">Current measurement under fairly minimal load, connected between buck converter and \u03c04, booted with Zoneminder running (reads 1.02 amps)<\/figcaption><\/figure>\n<figure style=\"width: 900px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201127t1650_7_1284_100.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/garfnet.org.uk\/cms\/wp-content\/gallery\/20201100-zoneminder-pi-experiment\/20201127t1650_7_1284_100.jpg\" alt=\"Our back yard, captured from 1080p camera at dusk - even quite cheap security cameras do Infrared.
