This configuration is pretty ok for a desktop replacement, especially if you're on a tight budget. A4-5300 should be enough for daily browsing routine, office applications and even casual gaming. Don't expect to run the latest games on this, but also you won't be disappointed with the included Radeon for some older ones or with medium settings. The possibility for OC is there, but I didn't test it yet. The case is good quality and overall the pc is quiet.
I didn't care about storage, the existing 500gb could be easily extended (internal HDD, there is already space in the rack for it) or with external drives (4 front USBs and 6 in the back should be sufficient). The RAM is only 4GB, which might be not enough if you're running more demanding apps. On the bright site, an upgrade to 8-12 gb is not so expensive these days.
Delivery on time with serious packaging (box inside a box).
