Since you're in Canada, it seems you can now order the Yate Loon D12SL-12 from NCIX. I think it's 8 or 9 dollars. This would have to be for your CPU (?) though, since the case itself has only 80mm.
I noticed that you have an Asus TM-211. I am not sure that it was this exact model I saw or not (it looked great!), but this case might be on the small side, so make sure that you have room to fit the Ninja, since it is fairly tall (and basically large all around).
Ventilation might be a limiting factor since I don't imagine that there is much intake in the front, and the rear only has your PSU and 80mm fan to exhaust the heat. With cooler components it wouldn't be a problem, but a Pentium D and 9800 Pro create a fair amount of heat. Most members might recommend a change to a 120mm fan case, like the Antec 3000B ($50-ish if on sale), but sometimes you really like the case you have and want to keep it. Maybe making one of Bluefront's slot fan gizmos to blow in or suck out air would help? Some people also get creative with cutting out fan grilles and things like holes in the bottom of cases.
I'm not sure what you mean about the VF-900 being worth it or not, but I would keep that video card unless you plan on gaming, and your solutions are probably limited since you likely can't use large, wrap-around heatpipe coolers. Maybe read about how people like the Arctic Cooling solutions these days (it's been hot and cold on them). They are the same price or cheaper and would blow the heat out of the case, making cooling the other parts easier.
EDIT: AARRGH! I need to type FASTER!
