I have replaced a few parts with the newest and best in bold (your budget wasn't stated) and explained what they all do.
CASE: Corsair T600 White - This holds all the components.
POWER: Corsair Pro Gold AX1200 - Supplies power.
MOBO: ASUS Z97-PRO LGA 1150 - Motherboards connect all other hardware together so they can communicate with each other.
CPU: Intel Core i7-4790k - CPU = Central Processing Unit, consider this the brain of the machine, it passes instructions between other components and does computational work.
COOLING: Corsair H80 Liquid cooler - cools the cpu.
RAM: 16 GB Corsair Vengeance - Random Access Memory, RAM holds bits of data for as long as they are needed by running programs or holds them until they are moved to permanent storage (hard drives or ssd's). When power goes out, all data held by ram is lost. This is often called volatile memory.
VIDEO: EVGA 06G-P4-3787-KR GeForce GTX 780 6GB - Graphics Processing Unit, this does Graphics processing and work well in parallel, cpu's do not work in parallel processing so CPU's are bad for 3d gaming and rendering. GPU's are very important for running modern games.
HDD1: SAMSUNG 840 EVO 128GB for system drive (Windows 7 Ultimate 64-bit) - SSD's are much faster than hard drives and have lower latency which means everything is accessed faster and loads faster which is why they are great for your operating systems. They have limited write cycles so they are not good for things like caching, or recording FRAPS on. This is called non-volatile memory because after a power loss data is still available. The 2 hard drives below are also non-volatile memory.
HDD2: 2 TB WD Black Caviar (for programs and games) - Hard drive, best cost per GB of storage space. They are not as fast as SSD's but work great for storing files.
HDD3: 2 TB WD Blue (for storage) - The blue version is a bit slower than the black version but otherwise is nearly the same.
MONITOR: ASUS 25" 1080p - Displays a picture.
KEYBOARD: Logitech G15
MOUSE: Logitech G9x
