And people accuse me of writing blocks of text.
Not sure on the new Neo3-fr, the older P35 neo2-fr was a very nice lower cost mother board.
Should be fine for smallish overclocks as proposed.
The AC f7p was the best low cost cooler, until Akasa brought out the AK-965x3 which is both slighter better for cooling and costs a bit less, around £12
Also it does not suffer from the fan problems of the AC f7p, long term use has shown quite a few people having an issue with the ACf7p where the PWM function fails and the fan gets stuck permanently at full speed and it loud at full speed.
I agree with you on the question of What resolution?
eg If 17"-19" 1280x1024 / 1440x900 then a 4830 or 9800gt would be a better card to look at.
That PSU is over the top for what you require.
shouldn't need anything more than a good 450w
Have a look at the Corsair VX450w
However saying that I've just noticed ebuyer have got the nice OCZ Mod Xstream 500w on sale for slightly less than the vx450v

A nice buy and modular which will help in a small case like the Antec 300 with so little in it.
RAM pc6400 is a good price point and with the e8400 you should be able to get 3.6ghz with it. any higher and you'd probably want to look at faster memory and better cooling.
The down side here is the cost of the e8400 at around £130 it's a bit pricey.
You may want to look into an AMD system with the new Phenon II x3 as they seem to be pritty good and around £100
I'll leave others to sugest AMD motherboards
