Advice for a noob trying to do it big.

So about a week ago I finally worked up the nerve to buy the mountain mods extended ascension computer case, I got it with the Trinity 10x 120 mm fan holes in the front and the standard back. I do not have much experience in custom water cooling systems but I'm looking to go big. I am really looking for help, and a advice from some veteran water coolers and mountain mods users on the forum. I have a fabrication background in car restoration, so tools don't scare me, any ideas y'all have would be much appreciated! I have absolutely no hardware in terms of water cooling or fans for this case yet and I would also like to know what sort of Parts I should be looking at. But keeping in mind I am sort of on budget.
