I have a CM Cosmos and am starting to layout my loop. I love this case, lot's of room since I won't be using the 6 HDD cages and they will be removed. At this point I'm only going to cool the CPU and GPU (see sig.) and I'm wondering aside from the obvious price/complexity cons, are there any benefits to having individual loops? or other cons? Space isn't an issue as I'm sure I could put 4 loops in here. BTW I have two chevette HC's or one per loop if I go dual. I use 1/2" tubing and the blocks (yet to be made) are homemade and should be low restriction. TBH the only pro I can see going to dual loops is for cosmetics but I thought I'd ask.
