Couldn't resist the impulse and installed Ubuntu Mate 18.04 Bionic Beaver LTS 32-bit in this one.
Windows 8 was previously the OS, and I'm not sure if it was 64-bit or 32-bit, from what I read checking it with "Disks", before going nuts. My bet is 32-bits.
Of course I made some changes on the boot and BIOS after reading some instructions on different Ubuntu forums. Lost patience cause the BIOS menu was a "show off" with big logos and too many options to change (or not to touch).
Ended up dizzy and just give it a go just for the sake of doing it. It takes maybe half an hour for Ubuntu's desktop to show (if it shows), and 20 minutes for the menus to be visible, but then it works fine.
From what I wrote down it's a 3.8 GiB Memory and the processor is an Intel Core i3-2120 CPU @ 3.30GHz x 4. Motherboard is Gigabyte. It's a Western Digital HDD, 500 GB, made in 2012 (WD Caviar Blue). American Megatrends BIOS with the "show off" disabled (it run so fast I'm not 100% sure of it).
What other info should I provide first to get things going ? (if there's an option for this PC). I'm thinking creating a good usb installer to start with. (LOL).
