It looks fine to me!
I like the Lancoool series. I just got the newer PC-K57 and I love it. The PC-K57 doesn't come with the PCI card holder, but I bought it separately. Newegg.com - LIAN LI Lancool PC-K57 Black Steel ATX Mid Tower Computer Case
Your case is tool-less with good, if not great, air flow. It should be quiet with the fans it ships with. If you have all 4 fans going plus the CPU fan, you're more in the range of quiet, but not dead silent, I would suspect. Don't forget, it has an open top. Sound will come out. Still, an excellent case and choice.
Rear - 120mm 1500 rpm
Top - 2 x 140mm 1000 rpm
Front - 1 x 140mm 1000 rpm
You can't go wrong these days with an unlocked I5-2500k or an i7-2600k.
I've used the Samsung F3 HD103SJ and it was a speedy drive. I found the 32 MB cache to be be just fine. I loved the drive until I got into this SATA III madness and sprung for 2 WD drives. I should have kept the HD103SJ. Newegg.com - Western Digital Caviar Black WD5002AALX 500GB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
The only thing I see that you may want to improve on is the motherboard, in terms of slot flexibility and future card expansion. You're getting a full size case, you might as well get a full sized motherboard, provided it's at the same price or a few dollars more.
