I want to cut a USB cable in half and pass the the cable through a small hole inside my PC case. Then join then using a 12v DC connector. The USB A end will connect to the back of the motherboard and the micro USB end will plug into an IoT remote PC power button. I was thinking to use those 12v DC jacks to connect the positive and negative wires together, seems like a sound option but thought I'd ask.

Only because I have thesee connectors laying around.

Please ignore the 4 cables - just want to attach negative and positive

Please correct me if I'm wrong, but for a remote PC switch, won't you need another cable into the case, to connect to the motherboard front panel header?
If you purely wanted to get a 5V supply to power the module, could it have a core in this cable and connect to any 5V supply within the case, i.e. a molex?
What IoT module are you looking at?
 
Basically its this nifty little thing. Decided aginst splicing the USB cable's cables are like 26AWG and fiddly. Instead just bent the metal mesh a bit to allow the USB to go through.

Works quite well this device, has a little 433 button too.

Interesting unit, it looks to be based on an ESP8266 type module?
The USB connection could possibly be used to re-flash it, if you ever felt like tinkering!
Given the external antenna, for neatness, I may have considered keeping the module within the case, running the antenna outside and if I had a spare USB header on the motherboard, possibly used one of these, to power it...

That might be a shout, although its some chinese cheap stuff with god knows what the device might transmitting, I am tied to the Tuya/Smart life ecosystem and works very well with Alex and such. So maybe if i'm feeling brave could flash it. I have a second one I bought for my main gaming PC might try it. It cost like £14 from AE.

But that USB 2 to UBC A thing - its on its way - but intended to use for the OS USB drive - but might use it to power this! This is the one I got.
