1) The CPU and graphics card have their own fans, which will be more than fine for all-but overclocking. You'll ideally want some in the case too though, and that depends entirely on which case you're using.
2) You'll need to make sure your current case is ATX and not MicroATX (or some other non-standard size). For instance, if it's a Dell, the chances are you'll be stuffed, as most of their cases don't use the normal sizes and specifications of ATX. If it is only MicroATX let me know and we'll spec another motherboard up.
3) If you've only a couple of hard drives then I'd recommend
this, which is ridiculously over-priced at Komplett, but if you're in the UK, then you can get it
here for £20 less. If you want something a bit beefier, or you'll be upgrading to a higher-spec graphics card in the near future (1 to 1 1/2 years), then I'd grab
this, again £10 cheaper than at Komplett. Don't, under any circumstances, get a cheapy PSU. It
will come back to haunt you at some point.
4) Just use the onboard sound - it will be fine for 98% of tasks. If you must get a dedicated sound card, then it's given how good onboard sound is now, you're not looking at a cheap one. Probably £50 for the first step up from the onboard.
Just some notes on the other bits you've already specced. The motherboard is absolutely fine, though if you're not overclocking, then
this will do the job just as well (£6 cheaper at
Scan). If you do intend overclocking then personally I'd grab
this, based on the new Intel P35 chipset, which is excellent by all accounts. Unfortunately, the
equivalent ASUS board is £40 more (and has just gone out of stock). It is apparently a really stunning board though. If you do go P35, make sure you don't get the DDR3 board (P35 can use either DDR2 or DDR3 memory). Also if overclocking, then grab
this cooler for a half decent overclock (2.8-3.1GHz or so). It's excellent value for money.
The CPU too is fine (I have the same), but if you don't do much media work (where the extra cache, the only thing missing, makes the most difference) you could save some cash by getting the
E4400 or even the
E4300 for a few pennies less. All include the same retail fan, all are very quick (chances are you'll never notice to the difference to an E6600 without testing), and all have a high multiplier, so for basic overclocking, all you'll need to do is raise the Front Side Bus (FSB) and it'll be as faster than any Core2Duo (the X6800 included).
That RAM is horrifically poor. I didn't even know you could
get PC 2400 RAM. It's also ludicrously expensive, compared to where RAM is at the moment. I'd grab
this, which is excellent. Team is a relatively new player, but they are reliable and have frankly excellent value products.
If you aren't buying everything now, then make sure you get the RAM now or very, very soon. Prices are starting to go back up again, and if they reach the levels they were at (more than double what they are now), you've lost a lot of cash needlessly.Graphics card is fine too. If you're gaming on anything at around or under 1280x1024 it's a good choice at the moment. Just make sure you get the PCI-express version and not the AGP (some do fall into this trap, so it's best to point it out). Again, Scan have them slightly cheaper - standard
here, the one with video-capturing ability
here and there's a Sapphire with the excellent VF900 cooler
here, without the video capture, though it doesn't mention if the cooler is fitted or just included for you to fit (I'd ignore the picture and be shocked if it wasn't ready-fitted).
//edit: I'm at work, and this post was compiled slowly, so others have replied since. I would still get the X1950Pro over a 8800GTS. The GTS isn't that much faster, and is poor value in comparison (especially the 640mb one). The Crucial RAM, if it's PC2 5300, would be fine, but it's still nearly double the price it need be.
