Spec wise it should run FFXIV without issue. However given history with HP in the past selling generations of the same computer without addressing hardware defects I personally wouldn't buy it. Two that come to mind is a desktop series with defective motherboard that would stop recognizing drives connected to it and the series of laptops that would generate enough heat to cause the motherboard to delaminate and allow the components connected to it to peel off. Both cases HP continued to make and sell updated versions of the product while still using the defective component.

I'd research not just that model but the series that HP belongs to beforehand to see if people have been reporting issues with it's hardware.
