Hard Drive - Note you can get 2 of these and run them in RAID 0 giving you a noticable performance boost but I really dont think that will fit into your buget at the moment...dont get me wrong though this drive will still perform well on its own.

Video- now there a couple of choices here: given the fact that you are an RPG man not a ton of graphics power is needed....Even on world of warcraft the demands are not that high. But if having a new system means trying new games, id sure hate for you to get hooked on a demamding first person shooter and be under powered.....
So in that light i'll give you a couple options:
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1351110&sku=E145-5122 the 6600GT will run just about any game out there with ease and in my opinion is well worth the money...but if you already know RPG's are all your gonna play then these cards will suite you just fine.....and still be able to play most new games fine...

Total for these componants is $835.95 CAN with the the 6600GT...Less with the other cards....Id advise not skimping on any of the other componants I have listed.....That gives you atleast $165 for a case/power supply and any cd-dvd burner players you may need.....As for the case try and find one with at least a 400 watt PSU and good fan layout...Id try and find one for ya but a case is always a matter of personal preference...
ope I have helped ya out.....
Tigerdirect.ca is probably gonna be your least expensive route in canada but I promote that you try looking cheaper if you can find it...i wish newegg.com would start delivering to canada for you guys already.
