While I look for fan for my LZ7 , my mind was struck by an age old question.
Will AIO fit?
That was the beginning of my janky journey to fit AIO inside a LZ7, for science.

Today, I received Silverstone td03 slim, I chose this AIO because it is pretty slim and have slim (15mm) fan which mean I can put the fan inside the case and the radiator outside.

I don't actually measure properly before buying the AIO, but it actually fit the side panel well

My kind of mod is no mod , I removed the IO shield of the motherboard and pass the tubing through that hole.
Because every motherboard io is different, this method might not suit your motherboard, YMMV

that tubing curved... but it doesn't kink , so shouldn't be a problem.
I think the better implementation is by making a little hole beside the psu mount, but I have neither the skill nor the will to do that
.
I'll post the perfomance matrix later, it's definitely better during prime 95 vs noctua nhl9i + prolimatech combo.
Honestly, it kinda stupid using AIO for non K CPU, but this is for science, to show that it is kinda of possible
