Please help in identifying some components for a i7 SSf build

Hi, Im very eager to pull the trigger and buy the shuttle SX58H7 but i rushed into my last build which i am selling most of the bits off now apart from the i7 920, hdd, dvd, gpu. I really like the shuttle but price and some components are putting me off. I think a major factor is how great looking the shuttle case is and how easy it is but cant help but feeling there a better solution out there for a case, mobo, psu, cooling. Ive been looking at the Silverstone SG01B-W but doesnt look as good as the shuttle. Can someone please help in identfying a: -

case - thats better or as good looking as the shuttle - similur size
psu - around 500w-600w modular and ultra quite
mobo - looking at the asus gene bt reccomendations welcome
cooling - suitable heatsink for moderate ocing at 3.2 to 3.6ghz but has to be very quite - i already have a true 120 but i dont think will fit!!

Price is not a factor, am willing to pay for quality - so willing to spend Â£500 on the above as am very near to buying the shuttle and am quite expeirinced builder but first time with SSF

Please if you have built somethink you think i might like or have any ideas please help, dont want to make the sam mistake did on last i7 monstorous build

Will do a build log on here once im going. oohh and i dont mind doing a small watercoolng for setup if its reasobly priced and fits inside case. I want system to be sleek, very power efficient as is running almost 24/7, quite and moderate gaming

thanks and please advice
