I have an older 2X3 GHz Dual-Core Intel Xeon with an ATI Radeon x1900 XT 512MB. I am not too savvy on the hardware side. 1.) Is there anyway I could keep my case, optical drives, harddrives and just swap out the motherboard, graphics card and processor with more current pieces to make it faster/more modern? 2.) If not, can I just turn the whole damn' thing into a PC? I like the case and having multiple swappable drives. Thanks.
