My quest for a final decent FSX rig

Ok I want to buy a few parts from the local online site, then take them to my local puter shop to get em all patched together. I need some advice please.
Current system specs:
Normal PC box, nuffin fancy
MSI AMD K9N Neo-F Motherboard - Socket AM2
AMD 64bit Duel Core 6000+
4 gig DDR2 Ram 667mhz
XFX Geforce 8600 GT XXX
Audigy Value Sound Card
80 gig and 250 gig Sata Drives
Windows Vista prmium 64 bit
CD writer & DVD Player Combo
450 Wat cheap no name brand PSU
19" flat screen
Now I want to buy the following case from here, the case link:

Now the 1st question is, will my mobo fit in the case? Mobo is the MSI AMD K9N Neo-F Motherboard - Socket AM2
I also want to get a new power supply, link below:

2nd question, will the power supply fit in the case?
I also want to buy the following graphics card, link below:

3rd question, will the card fit onto my mobo and in the case. I understand it is a long card.
Also I would like to buy the following VGA cooler(Antec Vcool with Blue LED Extension Duct VGA Cooler), link below.

Will this fit onto my mobo? Is it needed to fit this or is the stock coolers enough?
I was told that the 6000+ CPU fits on my board but it does not utilize the full ability. I was under the impression if something fits it works 100%?
Things like the HDD's, sound card, screen and RAM will stay in the new rig.
I will keep my O/S as is.
I know it is alot but I would appreciate help. I dont want to buy parts that dont fit. All help will be sooo greatly appreciated?
Thanking helpers in advance. I know whoever answers this post in full would go through alot. I would appreciated it alot
