My desktop at work was running super slow and was outdated... I found this computer after looking specifically for the best specs a work desktop should have to multi-task and run dual monitors... This PC has been working hard & reliably for 8 months now with no issues at all. We bought a second one for a coworker, and I'm back to possibly buy a third. Functionality is a 10 out of 10 and the case doesn't matter because it's going under a desk.
