I am still running one too. (and a gen 1 cloud key)
You can get one for $265 on Amazon.
A month ago they were over $500 there.
I have no idea why/how.
Another user found a link to the same item that is still in stock https://www.amazon.com/RACKIDEA-Keystone-Patch-Panel-Silver/dp/B0B1QQSRRN?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A2V1VNOXRLIB4M
I have not purchased this, but somebody shared this link in another thread: https://www.amazon.com/RACKIDEA-Keystone-Patch-Panel-Silver/dp/B0B1QQSRRN?source=ps-sl-shoppingads-lpcontext&ref\_=fplfs&psc=1&smid=A2V1VNOXRLIB4M
I like this one: https://smile.amazon.com/Cable-Matters-Mount-24-Port-Keystone/dp/B0072JVT02

I got this instead. Yes, I know it's supposed to be hardware. No, I do not care, since I have not see any performance degradation for my application. (house) yet.
It fits snug and pair fairly well with the silver panel.
G3 flex works awesome in IR filter only if you have an IR illuminator like LONNKY IR Illuminator Long Range up to 330ft/100m,30-LEDs 850nm,IR Infrared Light for Security Camera, Waterproof, Auto ON/Off, Metal Housing, Long Life time up to 25000 Hours https://www.amazon.com/dp/B09D7HZD6Z/ref=cm_sw_r_apan_glt_i_ZX568R1477HCPJM56DGD?_encoding=UTF8&psc=1
To be clear, since this should just be standards, other things like this exist:
PoE+ to USBC Power Delivery Compatible with Tablet Computers Like Microsoft Surface Go, Google Pixel, and More (USB-C Power + Data) https://www.amazon.com/dp/B07XYFB9G1/ref=cm_sw_r_awdo_T4P8YPSYC9SSRX948DSD
I don't but my 15u Ravico is just about full.
Such a good rack and takes 10 minutes to put together.
I saw some people were using VisualPing.io, but when I set it up got a million false positives, I think someone else was using something to check the source for a key word like "in-stock" but not sure if they wrote that themselves or not. Let me know if you find a solution!
