Hey, I have never built a computer before. I want a really good gaming rig built my myself. However, I'm a little thick when it comes to these things. Please check the following list for compatibility issues, redundancies, cables needed, anything missing, and anything that would prevent this setup from working. Thanks in advance! Inside Case Optical Drive Processor HDD Memory Video Card Wi-Fi Card Motherboard Power Supply Outside Microphone Keyboard Mouse Monitor Speakers Thanks Joe88, updated with the power supply. I thought 800 would be good because I calculated wattage to be around 650 watts, and I plan on plugging a lot of things into the computer. However, the speakers are unnecessary, I'm not that keen on sound. It's not a home theater system. Oh, and thanks for the sound card tip. I didn't notice it had one onboard. Does it have a Wi-Fi card onboard too? Also, Sephi, I don't plan on using Steam. It's incredibly stupid and requires IE, which is essentially bloatware. I also prefer antimicrobial keyboards because then the letters don't fade. But thanks about the Blu-ray drive. I didn't plan on burning Blu-rays, I just didn't know it made that much of a price difference. And the mic is for voice commands, not online games. So no feedback. So I could just put this baby together and it would work? YAY! Please point me to the cables I need though. Oh, and please tell me if anything is overkill! EDIT: Links updated. Price should now be around $1500. And someone still needs to tell me what cables I need!
