im not going to say it was easy. at first i was really nervous about doing it. but i read ALOT about it to the point where i felt confident. if you take your time and do ur research its not too bad. For me it was worth it. i had a 8-10 degrees temp drop which should give me some more room to play with an overclock. if ur room is fairly hot its might not be worth it tho coz it can only cool as cool as your room is if that makes sense. my room used to be really hot (being summer in aus) but i spent $180 on a portable airconditioner off ebay. which was probably the best thing i could have done for this build. if i didnt get that i dont think i would have bother watercooling my pc.
