Also, I would rather go air cooled as its a little simpler setup OR would you all truly recommend a water cooled setup as I am not 100% against the idea if it really is much better?.
Sorry for all the questions.
Thanks in advance :)
Welcome to the forum. The majority of people on here use the 2.2Kw W.C. spindle as they are much quieter and as they are water cooled if you need to they can be run slower. The air cooled ones have a fan that slows down with the spindle and thus less air.

You don't need a lot of water to keep them cooled in my case I use 1 ltr with a very small radiator 130mm sq. with a 120mm fan attached.

5 ltrs without a fan is fine.
