Meshify would need fan replacement.
Corsair 600T is not as well built.
Fractal cases work well with air or AIO / CLC. Why are you asking? Are you planning on running a CLC? Honestly for most users a good air cooled system is a better option. They cost less, last much longer, make less noise. The only coolng component that can go bad is the fans. With liquid cooling the most likely thing to go bad is the pump, and if the pump goes there is no cooling so no system to use until pump is replaced .. and if it's a CLC the entire CLC has to be replaced .. way more expensive then replacing just a pump. But if it air cooled and a fan goes bad system still works at low load. Worst case is use any fan held on with rubber bands until suitable replacement is in hand .. air cooled is not as expensive to buy, lasts way longer, fan replacement is low cost, etc. Sure water cooling is the 'cool' way to go, but in reality most people using water would be just as 'cool' with a nice air cooled system costing much less, especially if it's custom loop. Custom loops are more of a hobby then a necessity. They are customizing a car, just not quite as expensive.
I don't call all AIOs 'AIO' because while all CLCs are AIOs, not all AIOs are CLCs .. and there is a huge difference between AIOs that are not CLCs and those that are CLCs. AIOs that are not CLC are much better quality, all have threaded fittings so hoses can be made to length or components replaced if needed, almost all have copper radiators, have pumps that flow more than CLCs and have a fill port to service coolant. They are pre-assembled and filled lower end component kits. CLCs are put together to never be opened up, have aluminum radiators, low flowrate pumps, etc. To date I have never tested/used a CLC that I kept in a system for longer than it took to test it. but I have a be quiet! Silent Loop 280mm (AIO not CLC) in one of my systems for couple of years now because its very quiet and decent quality.
