I currently have a Dell E521 but I have upgraded the CPU, PSU, Ram, GPU and sound card to the following. I game at 1440 x 900 resolution (Samsung 19inch LCD) on XP.
Athlon x2 6000 Windsor
PC Power and Cooling 470w
2GBs 800mhz Ram
Creative Sound Card
The set up currently works great, I play Far Cry2 on high settings with 4AA @ 40-70FPS and Crysis on mostly high settings with 2AA @ 30-40FPS.
The issue is I would eventually like to move to a tri or quad core CPU and rather then build a new PC from scratch. I would like to carry over as many parts as I can. So basically bring all the parts stated above as well as my hard drive, DVD drive, and DVD -R/RW burner. Then add all these parts to a new motherboard and case. Has anyone done this before with a Dell hard drive before? Are there any issues I should be aware of?
I'm also looking at the following cases and motherboard, any recommendations/reviews?
