Airforce33

ok here are my plans and I am asking you all if it would work. I have a 8200 dell well the PC800 memory cost way to much for me to upgrade to 1gb I have 512mb now. So I was thinking could I buy a new case with a good power surpply and a new mother board and buy 1GB of memory and a new CPU all new for the case. But is it possible to move the other hardware in my dell 8200 computer to the new mother board and new case? like my video card sound card CD-rom floppy drive harddrive modem ect... I am kind of new at doing this if there is a website to help me out that would be great. Also if you would like to give me any other tips would be great to.

OK THANKS FOR THE HELP. Well I am going to mainly use it for gaming. Also I was going to get the BFG 6600GT 128mb card for my dell so I can run Battlefield 2. Would upgrading this even be possible now? Also I am just starting to plan a new system to build I never done it before. For a beginner any tips that would help me out would be great. So for gaming what kind of rig would you suggest?
