Asus P5Q serie seems to be very popular and nice overclocking boards.
Here's table of major differences:

P45 chipset has enough lanes for one full speed PCIe 2.0 x16 slot so these dual physical x16 slot boards limit primary slot to eight lanes if there's anything in second slot. (which gets those cut away 8 lanes)
PCIe 2.0 doubles bandwidth so at least yet PCIe 2.0 x8 operation isn't limiting graphic cards but that might change with next major GPU launches.
So P5Q-E and P5Q Deluxe are probably the most interesting choises because third physical "universal" x16 slot can operate at x4 (non-2.0) speed without limiting primary graphic card slot in any way... but card in any PCIe x1 slots limits it to single lane. (bandwidth of one lane is 250MBps in PCIe "1.0")
I have 3ware 9650SE-8LPML PCIe x4 RAID controller so I've had to check that thoroughly and I'll be getting P5Q Deluxe because of Express Gate SSD. (ability to browse web in few seconds could be handy in case of need to check FMI's weather radar data quickly when thunderstorm is getting uncomfortable close for using PC)
If you want "drop parts in" case without need for silencing then Antec P180-serie would be very good. If you want about full metal contstruction (only plastic in wires) case Lian Lis has some door equipped silencing friendly cases but those need adding of damping mat.
For PSU Enermax Modu/Pro 82+ is very good serie of quiet PSUs, like nearly anything made by Seasonic. 500W is more than enough for any single graphic card PC.
Noctua NH-U12P and Thermalright HR-01 Plus are about best CPU coolers for use with quiet low speed fans.

(Noctua can take second fan so that would rise it above HR-01)
In HDDs it's down to Samsungs and Western Digitals for quiet HDD.

Don't know about shipping (I've limited my foreign purchases mainly to Germany) but inside EU it shouldn't be big problem.
