When do you actually need to start watercooling? I've got a titan air cooling my unit. And as nothing i have seems to tax my pc enought to need to overclock it, i'm not sure i see the point. I tend to run around 42 degrees. I bought a overclockers setup so i can quite easily turn on overclocking. That said water cooling does look the nuts, and therefore i want it. It comes after a 5870 and a Intel SSD on my shopping list.
Watercooling generally allows you to overclock further, makes for a quieter system and like you said it looks good.
it looks fun and interesting to do. i'm bored of buiding a PC that has some form of aircooler bolted onto it nowadays. at least with WC, you can pick and choose how it looks and what it cools.
You can watercool for many many reasons: 1. Perfomance - getting the best overclocks and most from your components 2. utter silience - passive kits 3. Looks - just to make your pc / mod look good. 4. because you can
Yeah i would doing it for 3+4. It would be nice to have one of those pc's that people go "oooooo" when they see it. Unfortunatly that means that watercooling is going to remain slightly lower on my list of things to buy.
Your HAF932 is plenty big enough for a WC loop. you could fit a few radiators in there easily. Now try working with a Antec 1200, and you'll find out that a big case does not necessarily fit watercooling with ease
