Made a ton of progress today. Turns out the 24 pin is not standard at all (shout out to Dell for some great circuit protection, as plugging a standard 24 pin in results in 12V going places it shouldn’t). I am working on a full writeup on how to properly make the 24 pin cable that I should have up tomorrow. I’ve also found that if you plan to use this motherboard it is a must to also buy the front panel I/O from the T5600, it is nearly impossible to figure out what pins do what. Link to said part: Front panel I/O. After fighting with the 24 pin all day I was finally able to boot the system and install Windows, but now one of my coolers is no good
