Picking a 16-channel external power connection

So I’m planning to put an Xbox power supply,

in a box,

I wasn’t sure exactly which box, so I got four, hoping one would work.
The sockets and pinouts vary,

So I will need to make three different types of cables, one for each version range: v1.0-v1.1, v1.2-v1.5, v1.6. But those vary only on the “motherboard side”, the connector that connects to a power supply in a box can be anything, and I can pick it. By my count the maximum cable requirement is 16 cables. So I’m looking for a recommendation for what power connector to install the on the box. Ideally something I can bolt into the box that can handle a couple of amps of DC and into which I can plug my custom cable. Craig? :)
Update: from here maximum observed current 8.6A. I would like to use D Sub Connector Housing, 25 Ways, D Sub, 3, AMPLIMITE HDP-20, Receptacle, Steel Body but I’m not sure if they’re rated high enough for the current.

How to Customize Firefox’s User Interface With userChrome.css

Today I read How to Customize Firefox’s User Interface With userChrome.css. You may need to enable with e.g. Firefox 69: userChrome.css and userContent.css disabled by default. If you change userContent.css you need to open your page in a new tab to force an update. I would guess that if you change userChrome.css you will need to restart Firefox (I don’t know I’ve only been using userContent.css).

I should be clear: there are two files: userChrome.css (which affects Firefox features like toolbars and tabs etc) and userContent.css (which affects web pages loaded in Firefox).

I’ve been using userContent.css to fixup CSS on various websites. You can limit your changes to a particular domain in this way:

@-moz-document domain(exploringjs.com) {
  a:visited { color: purple !important; }
