I tried installing server edition (9.04) on my old computer to reduce the overhead from GUI, but the LiveCD says something like "This kernel only supports x86-x64. You seem to have a i686 processor."
I will assume that x86-x64 is 32 and 64 bit, so it's eligible. So why can't this computer be installed upon?

If you don't have a 64-bit CPU you can't install a 64-bit OS. If the installer is telling you that the CPU is an i686, you have to install the 32-bit server version.

The disk says it's x86-x64. Doesn't that mean it's both?

No, the x86 just means that the processor takes x86 instructions. The 64 means that those instructions are in 64 bits, but your processor can only use 32 at a time, so you need the i386 (32-bit) version
