@Rules: Absolutely, send me more detailed info about your motherboard and RAM and I'll see what I can come up with.
@Falcon: IL-2, is that better than the first one??

If I'm not there on Friday I will be on Sunday!
@Mutz: Wow, that's almost exactly the same as the one I put together, same case and all... even the monitor is one I was considering, although I ran out of money before I got around to deciding. Still using my (ailing) 21" CRT for the time being.
The system there looks great and it's guaranteed to be stable with a pre-overclock. However, if you're feeling plucky, you could shave €200 or €300 off the total price of the mainbox by itemising the components, shopping around, and assembling the thing yourself, overclock and all. It ain't that difficult and I can help you out if you need any advice. I just tried it properly for the first time and have my system running stable @ 3.2Ghz, temperatures nice and cool too.
I had the components for an entire system in the basket at Overclockers and was seconds from confirming the order when I saw the final price including VAT and shipping, so it worked out cheaper for me to buy from the other sites I mentioned in the first post.
When I have a few bob to spare I'll be getting a TFT widescreen monitor and for me the best quality/price/size tradeoff is one of two LG monitors:
LG L226WTQ-SF - 22 inch
LG L204WT - 20 inch
I had my eye on the 19" you listed but the native resolution is 1400x900 which is a little small for a screen that size. The best picture quality (physical size versus native resolution) is supposedly obtained by a 20.1" widescreen in 1650x1050, like the L204WT above. The 226 is more expensive but after seeing the comparison between 19", 20", and 22" widescreens in a shop, the 22" was calling my name and begging me to spend the extra few bob. It boasts a 2ms response time as well; that's very impressive. The best cheap option is the HannsG 19" widescreen, available in a few places. It's been getting rave reviews.
Whichever monitor you decide to go for, I've found
http://www.into-lcd-monitors.com" onclick="window.open(this.href);return false; to have the best prices, especially when you factor in free 7-day delivery, or €8 for the 3-day option, and dead/stuck pixels return policy. OC.uk charges a hefty whack for delivery and you'll probably have a hard time returning a monitor if there are only one or two dead pixels.
Also you should keep an eye out in the 'computer hardware for sale' forum of

Good hunting!
