|First off, I would recommend NOT using any case with a bottom mounted power supply. Also, side, top fans are NOT necessary and interfere with proper ventilation. All that is needed is a single rear case fan of at least 120MM or larger and a power supply with good cooling. All better power supplies should meet the second need.|
Buying a retail CPU provides you with a better warranty and a cooler that will get the job done. No need for third party cooling solutions.
You don't need a separate wired network card. If you want wireless then just add a wireless card. This assumes you have a router that has wireless capability.
HDMI supplies sound to the monitor. If you intend to use sound sort of surround sound system then you don't want to connect using HDMI.
The speakers you list are crap.
The Corsair is a good choice with a 3 year warranty. Corsair has units with a 5 year warranty. The unit you listed has a single +12V rail, which is what you want.
I will leave the SSD drive, the graphics card, the CPU and the motherboard for others to comment on.
