All,
The Beta release of the 32-bit (i686) Architecture of CentOS-7 (1503) is currently on build logs.
Right now, only the boot.iso is available, but after some testing from the users here with feedback, we can spin another tree with fixes and actual installer isos.
http://buildlogs.centos.org/centos/7/os/i386/
updates are also here:
http://buildlogs.centos.org/centos/7/updates/i386/
Current known issues are:
1. If installing on a QEMU (kvm) i386 VM, you must modify the VM cpu to use "copy host cpu"

2. The gnome desktop will not exit or log out from the menu.

If someone can figure out how to fix this issue, it would be much appreciated :)
======================
Please report bugs on bugs.centos.org or to this Centos-Devel mailing list will we do the beta testing and lets see if we can find/fix all the issues before the full release of this arch.
Thanks, Johnny Hughes
