- Any mobo is going to have a decent onboard ethernet/sound card, so your basically throwing money away there.
- The 140mm fan is too big for the cases 120mm fan slots, get a 120mm fan.
- Unless you watch DVDs you prob don't need the DVD Drive, use a USB Drive for installation.
- The Hyper EVO 212 CPU Cooler is probably unneeded unless your going to be folding, can use the stock CPU Cooler or get a H80/premade watercooling loop if anything. Also be wary that this thing is HUGE, I have one and there is about 2mm of space between the side of my case and this thing in a mid-size tower. Since that case is 200mm wide and the cooler is 160mm tall, with the space for the mobo tray and risers there *should* be enough room, maybe.
- Get 2 sticks of ram. Dual-channel ram (DDR and up) work best on 2 sticks of ram, as they can allow simultaneous read/writes instead of waiting on either operation. Otherwise your ram is gonna act like garbage, and 8GB is small these days :p
- Consider a SSD instead of a HDD. Unless you plan on torrenting everything, you prob don't need this much room :p SSD will help your load times and make the computer feel faster.
Other than that, don't see any problems. The GPU/CPU are good picks, nice power for the value. Good PSU with 80+ Gold, modular is nice. Built in wifi is nice as well :p
