i hope i did ok. i have never really built a computer before. i have replaced parts before though. i use my computer for gameing, satelite tv, hdtv, burning movies to dvd, music, and internet. my monitor is a 32" samsung lcd, and my pc is also hooked up to a mitsubishi 720p hdtv projector projecting a 9' x 5' screen. i will be running vista 64bit ultimate, unless i have major issues, then i will run xp 64bit. this is what i just ordered and should have by this weekend. oh and the video card i already have. its a evga 7950ko 512mb.
I have the same HD's and case...the big drawback to the 900 is that the drives aren't on rubber grommets, hence you can hear them VERY well. I put some felt door-stops in between the drives and the drive-cage and it helps some, but they are definitely the loudest thing about my PC.
