Which case for a Conroe build?

[daddyorchips]

Need a case recommendation from you guys. Am putting together a new Conroe build, which I'll list here now:-

Conroe E6300 or E6600 (undecided)
Gigabyte DS4 Mobo
2GB G.Skill HZ PC6400 Ram
Scythe Ninja Fan
Akasa Amber: 120mm + 80mm Case Fans
Creative Xi-Fi OEM
Some LEDs
Sapphire X1900XT-X
Pioneer DVD-Writer
Samsung 250GB SATA HDD x 2

Here's the case/psu option I was considering:-

Lian Li PC7+ Case + CD-Rom Bezel + Window - £89
Seasonic S12 600W Silent ATX2.0 PSU - £99

However, quite a few users have suggested the following, which has prompted me to make this post:-

Antec Sonata II Piano Black Quiet Case - 450W Smart Power PSU (CA-040-AN) - £77.49


There's a £100 difference between these two, so I'm wondering whether it's worth the difference. I do like the though of having an aluminium case (Lian-li) as having come from a Shuttle (SN25P), I'd quite like my PC to remain light(ish). But is it worth the price diff?

Cheers!


EDIT: The 600W PSU may seem like overkill, but I'm assuming it may future proof me when faster graphics cards/CPUs come out. Perhaps not though...?

Is there any foreseeable reason why I would need a 600W Seasonic? How close to those 500W do you think I'm at with the above setup? I don't think I'd ever go down the SLI/Xfire route, but I guess CPUs and newer graphics cards may have greater demands in the future.

Yewen,

How noisy do you find the LED lit fans in your PC7+? Also, what cases that cost £100+ would you say beat it?

I had a look at the other Lian-Li cases, but some of them look pretty damn fugly!
