If you are operating a business or in any position where hardware reliability and uptime is critical, you can rest assured that the Obsidian contains only the best of the best when it comes to PC components! Because we limit the hardware in the Obsidian in this manner, we are also able to offer a level of service unmatched among our other computer lines. We can provide expedited, full system replacements in the rare event that an Obsidian fails during its parts warranty if a quicker solution is not available.
