I'm getting a Cloudflare error page on that link: 'The owner of this website does not allow hotlinking to that resource'

Huh, didn't realise it spits out that kind of an error. I guess Cloudflare whitelists your IP address if you visit it once since that links still works for me without visiting the original URL?

Anyways, you can see the photo here: https://www.kitguru.net/components/leo-waldock/phanteks-evol...

Yep, it's probably the deep linking protection. It probably doesn't like the HN referer

I could open the link in a private/incognito window.

Same here

Wow, this is almost exactly as I wanted (except I wanted a horizontal mount akin to blade servers). Never seen it, thanks.
