Teehee. Other means. The G710 is a mechanical keyboard. If thats what you're looking for, go for it. I have a G510 which has macros that I use often in many games and even in hammer, and it has a neat little monochromatic LCD you can use for whatever. I just use it for time and monitoring of hardware (temps, workload, etc) but lots of games have applets that work with it. All depends on what you want.
If you want responsive and abuse taking, get the 710. If you just want a nice looking backlight board, go with cow. If you want some macro keys you can bind and a screen to monitor your computer, get the 510.
Now, as for the parts, here's a combination of hardware that will give you the power you need and are reliable, and all from the same place so you dont pay $100 on shipping from multiple spots. I compiled this list with moderate budget in mind as well as the help of my roommate who does this for a living and my buddy who is a computer enthusiast:
Power (Is adequate for this setup and some upgrades in the future)
CPU (If you like intel, go for that but you'll need a diff mobo)
Video Card (wont let you down)
Memory (I've seen Planetside hit the 3.5gb mark, this is cheapter then 6gb)
MoBo (this board has loads of room for expansion)
HDD (Nothing too fancy. Will load games just fine)
DVDD (Basic but will work just fine)
As for the operating system and case, I'll let you decide what you want to do.
All this will be about $810 before taxes and shipping. Add on windows 7 and whatever case you want and you're looking at somewhere around $940. (assuming 100 for the OS* and 30 for your case)
