This is a powerful computer ready to work. It is a workstation computer, meant for heavy tasks like photo editing, video editing, CAD, and more. It is set up with an SSD boot drive that is also big enough for many programs and 2 1TB HDD's in a RAID 1 format to back up your important data. I have completely gone through it to check for correct function. It has been cleaned. It is fully updated with drivers, bios, and the latest OS updates at the time of this post. The OS is a fresh install.
