my ceilings in this room are also 10 feet high. so can i get away with the cheaper ones or will it cause a massive heating problem. looking for any help available

well id probably go for what I can afford!
the more exspensive ones have an adaption for a cooling kit! which may come in handy
If your planning on running 4x 1000w it dont matter which kit you
choose. your room is going to get hot!
you want to look at keeping it all cool as well

thanks oj the 200 are more in my price range right now. so i'll probably go that route and by a nice a/c to keep everything cool.
