Sorry, but when you make false statements like you just did I will continue to post what is factual/truthful. There are many things definitely different between AIO and CLC than just a fill port. They also have threaded fittings on all components hose fittings that the hose can be shorted and/or changed components components can be removed/added as needed. have copper radiators while CLCs all have aluminum radiators some have quick disconnect fittings in the lines. AIOs that are not CLC also have definitely different pumps than CLCs do. They are not Asetek or any other CLC OEM. Swiftech AIO pumps are basically one of their lower end component pumps, can't remember the model number right now. Aphacool AIOs includes be quiet! Silent Loop and Fractal Design Kelvin (no longer being made) AIOs. The Alphacool Eisbaer uses one of their DC-LT pumps on older units and new ones use Eisbaer LT (Solo) pump found in link below. https://www.alphacool.com/shop/cpu-cooler/intel-amd/20228/alphacool-eisbaer-solo-2600rpm-black Newer Alphacool Eisbaer use Eisbaer LT (Solo) https://www.alphacool.com/shop/cpu-cooler/intel-amd/23937/alphacool-eisbaer-lt-solo-black?c=20571 Below is a link to video of user replacing the pump in his older Alphacool Eisbaer AIO.. https://www.youtube.com/watch?v=nzdisSGcJBE Along with Alphacool Aisbaer series there are Aisbaer LT with quick disconnect fitting inline to make it easy to add/remove extra components and Eiswolf GPU AIOs. Alphacool also have GPU waterblocks with quick connect fittings already filled with coolant to be mounted on GPU and connected into Aisbaer loop. Hopefully once you look at all these other AIO lines you will begin to understand why we have AIOs and CLCs and why people like AsetekDennis use AIO and CLC for the respective coolers they are and not lumping them all into one group.
