Yes to 212 and wifi.
I'd look at other boards in the OP, the LX is poor value on its offerings. I don't think the LK is sold where you are.
I'd also look at getting a $50 case and $60 PSU if possible, but that combo could be a lot worse. If you like the case that's fine.
Ahh I misread the OP and thought I had selected the motherboard mentioned there, thanks for that. Couldn't see the one that was actually mentioned so you must be correct about it not being sold here, so I added:
MSI Z77MA-G45 Z77 Socket 1155 8 Channel HD Audio mATX Motherboard
also switched the HD7850 from PowerColor to Sapphire.
Planned build now looking like this:
CPU: Intel Core i5 3570K 3.4GHz Socket 1155 6MB Cache Retail Boxed Processor
Motherboard: MSI Z77MA-G45 Z77 Socket 1155 8 Channel HD Audio mATX Motherboard
GPU: Sapphire HD 7850 2048MB GDDR5 PCI-Express Graphics Card [11200-00-20G]
RAM: Corsair Vengeance 8GB (2x4GB) DDR3 1600Mhz CL9 1.5V Non-ECC Unbuffered
Storage: Samsung HD204UI Spinpoint F4 2TB Hard Drive SATA 5400RPM 32MB Cache - OEM
Case & Power Supply: Coolermaster Silencio 550 with GX 550W PSU
Optical Drive: Samsung SH-222BB 22x DVD±RW DL & RAM SATA Optical Drive - OEM Black
Other: Tenda Wireless-N300 PCI Adapter, CoolerMaster Hyper 212
Yeah I do like that case, I was looking at that one and the fractal design R3.
edit-Although I like the look of the BitFenix Shinobi from the OP too so may switch to that and a "Corsair TX 650W V2 PSU - 80plus Bronze Certified" which works out at roughly the same price. In fact I'm pretty sure I will.
Thanks for running an eye over it.
