Welcome to the forum.
I am not a HP employee.
This question is hard to answer without knowing additional information.
You need to know what: size, the location, and the number of fans the chassis can accommodate. You also need to know if the chassis can accept 240 mm and 280 mm fans and associated radiator. Many HP systems can only do a 92 mm fan/rad setup.
Then you also need to determine if the PC shipped with a MB backplate behind the processor socket. If not, can you remove the rear side panel to install a backplate provided by the AIO liquid cooling manufacturer. No removable side panel means you will have to remove the MB from the chassis to do the backplate.
A HP provided CPU Fan/heatsink may also not require a backplate to mount to the MB.
Unfortunately HP does not always provide this information. I did not see any specs on the above listed at the Best Buy link you provided.
I can tell you many HP PCs use 92 mm fans. I am pretty sure the i7-8700 processor can use a stock Intel fan. This means there may be no processor socket backplate.
This is a new system. The only person that can answer your question would be someone who has swapped in a liquid cooling solution.
I would look for a liquid cooling system at purchase if this is what you want.

You're very welcome.
There are too many variables. You really have to examine the case to do some measuring. You must install a processor socket backplate if the PC does not have this pre-installed. You need the backplate to secure the pump assembly to the CPU and MB.
HP does outsource to Asetek (Link) for liquid cooling components. Asetek has 92 mm and dual 120 mm (240 mm total) AIO liquid cooling systems.
It is wiser to buy a HP PC with the components you want or build a DIY system.
