If we get the T1-reference for it's better 3080FE suitability, are we still able to fit an AIO 240 or 280 to cool the CPU? I assume not as the GPU will be in it's position in the T1-Reference. Or can it fit somewhere else?
You can fit a 280 radiator in T1-Reference.
You can also fit a 280 radiator in T1-Sandwich.
