Good choices for the most part. I would say go for a Seagate 7200.7 120gb HD. I have two in RAID 0 and couldn't be happier. What will the rig be used for primarily? If for gaming I would suggest trying to obtain a plain vanilla 6800 or an X800xl. Also look for memory with good TCCD chips. I'm a Geil fan myself. You'll be hard pressed to beat the XP-120 with a good low speed 12cm fan. What case will you use? This will be a huge factor in keeping your rig quiet. If you need more help... just ask
