I lowered the Libreboot 9020 price: base spec was £398, now it's 338. Also: MT variant is now available in the drop-down menu. SFF is ITX/compact form factor, ATX is a full tower.

Libreboot preinstalled, replacing proprietary BIOS/UEFI, offering greater security and fast boot speeds. I'm Libreboot's founder and lead developer; sales fund Libreboot. Debian Linux preinstalled, but you can request a different distro or *BSD*, e.g. FreeBSD, OpenBSD, NetBSD.
