I already have an IBM Aptiva 720 with a 75mz CPU, what problems would I have to look into if I just wanted to buy a new case, motherboard and CPU?
Computer Doctor:Your Aptiva system most likely uses an LPX form factor motherboard, which is unfortunately a proprietary design. What this means is that there are no other available motherboards, power supplies, or cases that will interchange with yours. The drawback is that this essentially renders your system as non-upgradeable, at least as far as those main components go. The good thing is that since your system currently has a Pentium 75, you can probably upgrade it by changing ONLY the processor and get up to at least 200MHz (possibly more). Your motherboard probably has a Socket 5 design for the processor, which means it supplies 3.3 or 3.5v to the processor. To upgrade to 200MHz, you will need a socket capable of providing 2.8v to the processor (Socket 7), or a special processor and voltage regulator adapter combo that will allow the lower voltage processor to work in your socket. Intel makes such a processor called an “Overdrive” Pentium MMX processor, which is available at spe
