[CentOS] Minimum RAM requirement for CentOS 6.x graphic installer?

Hi,

The title says it all. What's the minimum RAM requirement for the CentOS
6.x graphic installer? In our public libraries we have some old hardware
running CentOS 5, and I wonder if some of these machines can be upgraded
to CentOS 6. Unfortunately RHEL 5.x' nifty text mode installer got
seriously crippled with version 6.x.

Cheers,

Niki Kovacs
