which one should i download?
 

http://centos.arcticnetwork.ca/

here i can see many links. i have a 32 bit computer.

i want to install centos for server edition. not for desktop.

which one should i download from this list?

http://centos.arcticnetwork.ca/6.2/isos/i386/

the minimal or dvd binary iso will get you going.

thank you very much.

Get the 2-DVD set from http://centos.arcticnetwork.ca/6.2/isos/i386/ (it comes as a torrent only from that site). The installer gives you options for the sort of installation you want, including plain server, data-base server, and web server. That's probably easier than using the minimal and guessing what to add, or using the live disk and getting a GUI.
