This setup good for multimedia?

Main usage:

Video - youtube, HD, 4K bluray movies
Audio - MP3
MS office
Surf net and downloads
Ebooks

Here's my plan:-

Thermaltake Versa G1
Intel Core i5-4570
ASUS Z87-K
Palit GeForce GTX 750 Ti StormX Dual
G.Skill RipjawsX DDR3 PC3-1700 (F3-17000CL9D-8GBXM)
Cooler Master G500
Western Digital Black (1TB)

I wonder if there's an inbuilt WIFI card for the mainboard?

This system stable?

Is this overkill?

It's the cheapest part i can find from HWZ pricelist already.
