Okay, so the Antec Fusion case isn't a replacement for their Aria case. At least, it doesn't look like a direct replacement (see yesterday's updated post for a picture).
Unless Antec decides to update the Aria, which has a PSU rated at only 300 Watts, I will have to look for a "mini-tower" [Isn't mini-tower like saying "jumbo shrimp"? But I digress - ed.) case instead. I can get a mini-tower for about $30USD and add my own PSU (probably an Antec Neo 430) for less than the cost of the Aria. The downside would be that a mini-tower is larger than the Aria. Sigh.
Although I have some time before I need to decide on which case to get, I will need to do so, soon.
