One other thing you'll want to consider upfront w.r.t a hardware purchase is whether or not you want to support live migration.
http://docs.openstack.org/cactus/openstack-compute/admin/content/configuring-live-migrations.html For this you'll need a large amount of shared storage (usually via NFS) where the instance files will live. Whether you choose SAN, NAS, or just a node with a bunch of disk is likely dependent on your environment and budget.
