watercooling - rad on output or intake ?

[mortals]

I'm thinking of building a new system soon and possibly going for a watercooling setup. I was going to go for watercooling when I built my last case but was put off by the price etc.

Well here is my basic question: on placing a radiator inside a case, which is best?

1. To have it on the intake
This means you get cool air at room temperature, downfall being the rad heats up the air going into the case, meaning a higher case temperature and therefore heating up other air cooled components

2. To have it on the exhaust/output
No effect on the air cooled components inside the case, average case temperature is maintaned (altho aircooled components still heat the air).
Downfall being the radiator gets warmer (few degrees?) air going thru it, altho it should still be effective at cooling

The way I guess to get around this is to build a seperate radbox but then that possibly means a bigger system with further for the water to travel

Not sure if either way is better than the other or if it's just 50/50 but I guess it depends on the number of air cooled components in comparison to watercooled aswell as airflow etc.

components not cooled by water: RAM/PSU/HDD(possible,but not used much?)/mobo components

Cool sounds like both ways work just as well.

I was thinking of going for a dual 120mm rad at the top of the case so the warm air from the radiator leaves the case. I think there are too many other components that need air cooling. I'm also not sure whether to get a gpu block or not. I might go for cpu and northbridge.

So far I am thinking of going for a midi case as full towers mean more air to move and also take up loads of space. There don't seem to be many nice looking cases around atm.

I will probably build everything from new components. The spec I am thinking of so far is:

Intel Core 2 DUO E6600 "LGA775 Conroe" 2.40GHz (1066FSB)
Gigabyte GA_965P_DS3 (Socket 775) PCI-Express DDR2
Thermaltake VC3000BWS Armour Jr SuperMidi Tower - Black
G.Skill 2GB DDR2 NR PC2-6400 (2x1GB) CAS5 Dual Channel Kit

ATI X1800XT or Geforce 7900GT (not sure atm due to linux support for ATI)

Water Setup:
1/2" setup?
Dual 120mm Rad (Thermochill PA 120.2)
Aquatube Res
Pump (arg not sure which )
Water Wetter
240mm Guard
775 Waterblock (not sure which atm? - Swiftech Apogee Extreme Performance)
NB Block (also unsure)
GPU Block *might just go for NB/CPU to start with

The gigabyte boards look good, the only thing I noticed is there might be trouble using a watercooler for the northbridge on the higher spec ones as they have massive heatpipes

I'm moving house atm, so probably won't be building it for a while. Also from what I hear, I'm not going to be able to get a conroe for a month or so.

ATM I'm just getting some ideas looking at the size of some of the rad's, I'm not sure if a midi will be big enough. I like the CM Stacker 810, possibly will get one of those if I can, the 830's look ugly .

I will probably post a project log, similar to my last case I built 2years ago

The pumps seem a bit of a minefield aswell. The swiftech one is meant to be good but from what peeps have said it is noisy might end up getting a eheim/hydor.
