I'm using the Abko Suit Master P1000 case, which is rated for a 240mm AIO. Currently, I have a 240mm AIO installed, but my i7-14700K is overheating, so I'm considering upgrading to a 280mm AIO. The specs say the top supports two 140mm fans instead. Does that mean there's a chance I could fit a 280mm AIO there, even though it's not officially supported? Any advice would be appreciated!

It's likely that if your case isn't designed for a 280mm AIO, it might interfere with your motherboard or RAM. These AIOs are usually about twice as thick as standard fans, so you could run into clearance issues. For reference, my 280mm AIO barely fit in a case that officially supported it, and it still hung down quite a bit.
As for fitting a 280mm AIO in a case rated for 240mm, you should be cautious. Some users have managed to do it, but it really depends on your specific layout. Make sure to measure the area, especially around the RAM and VRM, just to be sure you won't run into any heat issues.
