eRacks primarily focuses upon pushing high-end, rackmount servers that run various Linux distributions (Ubuntu, Debian, CentOS, Fedora, et al) along with popular BSD operating systems like NetBSD and FreeBSD. However, eRacks also offers a limited range of branded laptops/notebooks, firewall servers, and other products. Their newest laptops from eRacks are Linux-loaded versions of the ASUS Zenbook laptops and ultrabooks. My main system right now in fact is a Haswell-based Zenbook. Servers from eRacks have options for both AMD and Intel processors.
