O. K., as I said, Linux is a OS that runs on x86-based systems, so here are the system requirements of the LinuxOS.

• 32-bit x86 processor (386, 486, Pentium, Pentium MMX, Pentium Pro and Pentium II. Also supported clones such as Cyrix, AMD and TI)
• ISA, EISA, PCI or VLB Bus.
• 4MB or more of RAM
• 1 1.44MB or 1.2MB floppy drive
• VGA Compatible video card
• 40MB of Hard Disk Space (after installing all modules)
• CD-ROM drive, in case you purchased a Linux CD-ROM.

Where do I get it?

Wow! That's a question I can't answer until you've seen the distributions
