My First Build

I am looking into these parts for my first build. Please tell me if these parts are good. Also I found them all at Newegg but if there are better prices else ware please include that. I live in the USA.

Thanks

Case: CM Storm Trooper

HDD: WD blue 1 TB

SSD: Seagate 600 series 120 GB

CPU Cooler: Thermaltake Water 3.0 Extreme

PSU: Cooler Master Silent Pro Gold 800 W

RAM: G. Skill Ripjaws X Series 8GB

CPU: Intel Core I7-3770K Please explain the K thing I am really confused.

Motherboard: ASRock Z77 Extreme6 LGA 1155

GPU:HIS iPower IceQ X (squared) Radeon R9 280X 3gb

Monitor: ASUS VS Series VS247H-P Black 23.6"

Keyboard:Logitech G510s 920-004967

Mouse: Logitech G700s

diffrence between the i7-3770 and 3770K is that the K means its an unlocked processor. That means that the i7-3770K has an unlocked multiplier so is easier to overclock then the i7-3770 with a locked multiplier.

For the rest build looks good,

Thanks for the reply I thought that the K was some sort of measurement unit. :-D
