holy crap
thats hot...

Alright...after doing some more talking to people, I got a recommendation as for a barebones cooling system:

BlackIce Xtreme Pro Radiator
PolarFLO Black/Copper waterblock
Rio 180 Pump (search for "180" on that page)

Those three components come to about $126 before shipping, by my calculations.

The guy said something about having to modify the Rio 180 so it would work as an inline pump?

Also, I figure I need a reservoir, or something, and some tubing?

tygon is the best tubing you can get for your comp basically
clearflex 60 and 70 are pretty good from what i heard and much cheaper than tygon but still comparable to it

so check that out

i think reservoirs can be homemade easily if you have the time
here is a good read

i want to get the hydor L30 pump
much quieter than most of the eheims

it can be used as inline or submersible
i think it would be much quieter in water than just sitting in your case as the resonance gets passed on easily

Hrm, I really don't have the time to make a reservoir by myself, so I'd prefer to just buy a good one...

try to get the one from innovatek
it seems like a well made one and has been around long enough to prove its quality

if you have a pump that is submersible, you might want to put it in a big reservoir as well so that dampens the vibration of the pump and also makes things easier

Should I do anything differently, from the beginning, if I plan to (possibly), at some point, watercool my gpu and hard drives?

there are reservoirs with 2 sections
that is quad fittings for extra cooling of your hdd and gpu

btw
for that rio 180 pump, you have to make sure it uses 1/2 fitting if you are using 1/2 piping
