These are the components in my current gaming rig. This will be changing very soon, but as of the time I'm writing this it is accurate. It should also be noted that this system is quite old and therefore out of date compared to top tier systems available today, but it's mine and I'm proud of it.

Motherboard	Gigabyte K8N Pro
RAM	3 x 1 GB sticks of 400 MHz DDR RAM
CPU	AMD Athlon 3200+ overclocked to 2453 MHz
CPU cooler	I don't know the model of the heatsink I have, I do know it is an older model made by Cooler Master. I have 2 Scythe Kaze Slipstream 120 mm fans running up to 1900 rpm and pushing up to 110 cfm (cubic feet per minute) of air though that heatsink. The fans are hooked up to a Sunbeamtech Rheosmart 3 Fan Controller to help keep electricity costs down during hours of light use.
Hard Drives	My operating system is on a 500 GB SATA Seagate Barracuda hard drive. My media is on a 2 TB Seagate Barracuda SATA hard drive. I have a 160 GB Fujitsu (Fujitsu sold the hard drive part of their company to Toshiba) SATA hard drive with nothing on it sitting in the StarTech SATADOCK525 hot swap bay. I have 2 Western Digital PATA hard drives, one 80 GB and one 160 GB. In addition to the Silicon Image 3512 SATA controller chip on my motherboard I have a VANTEC 2-Port SATA 150 PCI Host Card w/RAID with the same chip.
Graphics Card	Sapphire X800 GTO with a GPU core overclock to 414 MHz and memory overclock to 510 MHz.
Sound Card	The sound card I'm running is a ASUS Xonar DS 7.1 Channels 24-bit 192KHz PCI Interface Audio Card.
Sound System	The sound system is a Panasonic SC-BTT268 5.1 Channel 1000 Watt Home Theater System with 3D Blu-ray Disc Player. My neighbors just love me. I like my music and movies to bump!
Case	NZXT Alpha mid tower case.
