There's no point in getting an expensive graphics card with lots of RAM - they're specifically designed for 3D gaming, and will make little to no difference for 2D desktop work. Any old ATI or nVidia will do the job as long as you're not looking for a games machine.
As for storage:

These are awesome. Two drives that automatically mirror, low power consumption. It just appears as a single network drive that you work from, and everything it automatically replicated across the two drives by RAID. It's also always on, so you can use any device to read from it - tablet, phone, laptop, desktop etc.
As for your question - is it any good? The answer is: It's ok. It's got a lot of fancy phrases in the name, but at the end of the day it's a fairly low budget pre-built system, and it's AMD - which has slipped behind Intel (unfortunately).
