should always contain components that are upgradable and of good quality; some components displayed can be upgraded, while others (eg: the PSU), might be stressed from the get-go.
Not knowing fully what your budget is I can only offer up some options on the current list of components you have listed (based on: User Reviews, Price, Upgradability, Quality).
1)PSU ($75-$100, over 500 watts, Brandname, User Reviews):
2)Hard-Drive ($$50-$75, Speed, 5 year warranty, User reviews):
3)Computer Case (this is strictly a personal choice; but imagine getting what you thought was a bargain price for a decent case, only to find it's a total nightmare to install the components into. Here's a variety of mid-tower cases in the $75-$100 range, that have good-great reviews):
1) COOLER MASTER Storm Scout
2) COOLER MASTER RC-690
3) Antec Three Hundred
4) LIAN LI Lancool PC-K58W
5) COOLER MASTER Gladiator 600 RC

If you post whether you're in Eastern or Western Canada, I'll be able to provide more links for products available in that region...being a Canuck myself.
I will be building a new desktop computer soon. I already have a monitor, keyboard, and mouse, and my university actually offers Windows 7 for free legally.
I want my computer to do a bit of gaming because I do play WoW, and it is important that I don't lag at all.
Anyways, here are the parts I am thinking of from newegg.ca (Yes I am canadaian)
