Two kinds of RP-SMA dual-band WiFi antenna parts having :
- Y9MPH is an omnidirectional dipole stick antenna which most use
- 3TJ9N is a semidirectional patch/panel antenna on a wire which few people use but can be useful when you want to put the antenna into a place having better signal reception
Both are also supposed to work for Dell OptiPlex Micro models 3020/3040/3050/5020/5040/5050/7020/7040/7050 (as 5030/7030 models were never released and 3030/9030 only released as a different all-in-one PC form factor): basically the end of the Micro form factors in Dell OptiPlex Series 4 and start of Dell OptiPlex Series 5.

Not all virtualised hardware (older hardware usually has died by now) conforms to the Windows 11 minimum specifications.
So here are some links that should be of help to still get Windows 11 running on those:
If you insist on running older hardware that has a TPM header on the mainboard:

I have seen too many sites where cabling was laid en never tested before actual use, which meant locating the cabling and faults was a nightmare.
Be sure to have good (which can be very simple, but more complex when Power over Ethernet is involved) testing hardware and use it during installation. You will thank yourself later.
A few videos that can be helpful:

I have been contemplating on pfSense hardware as there has been a large shortage on that market especially for having more than 2 ports (similar to for instance Mikrotik PoE router unavailability).
If by now I have not found any, I might want to revisit [Wayback/Archive] Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up – CNX Software has 3 RJ45 ports and 2 SFP+ cages.
They found it via this 4 page review:

[Wayback/Archive] GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support which can do many-to-one port mirroring.
This is a newer and cheaper hardware revision than the:
- GS105Ev2 (which is managed and can do port-mirroring, and is confusingly sold as GS105E-200) which in Germany already is end-of-life
- GS105Ev1 (which is unmanaged and cannot do port-mirroring and is confusingly sold as GS105E-100) which is end-of-life but still sold
Via [Wayback/Archive] Everyone Should Have One of These – EASY Packet Capture! – YouTube who explains very well why you need a switch that can do port-mirroring, then recommends the GS105E but forgets to mention:
- there are different revisions of the GS105E with the above drawbacks
- there is GS305E

Dennard scaling – Wikipedia
Since around 2005–2007 Dennard scaling appears to have broken down. As of 2016, transistor counts in integrated circuits are still growing, but the resulting improvements in performance are more gradual than the speed-ups resulting from significant frequency increases.[1][10] The primary reason cited for the breakdown is that at small sizes, current leakage poses greater challenges and also causes the chip to heat up, which creates a threat of thermal runaway and therefore further increases energy costs.[1][10] Since 2005, the clock frequency has stagnated at 4 GHz, and the power consumption per CPU at 100 W TDP.

This is a reminder to check if this below late 2019 proposal inspired by Visual Studio Code Screencast mode¹ already made it: [Wayback/Archive] Overlay of commands / shortcuts / keys pressed – Screencast Mode · Issue #981 · microsoft/PowerToys · GitHub which mentions some tools that can already do this
Here is a list of FOSS apps that currently do this (sorted by stars):
To add to this list (unsorted):
In the meantime, I am using Key-n-Stroke as it is the only still supported one I found that is easily turned off/on when typing sensitive content like passwords:
