Antec 600 build - re: 2 screws per fan

[hfxmike]

pics and captions are here: Picasa Web Albums - Mike Graham - 600 fans

This is my first complete build - still not done - cable management looks tough with the bottom mounted PSU and the header cables coming from the top.

My main question is ...did I install the side and front intake fans correctly? I don't understand why Antec only allows 2 screws for the fans. I think I mention it in every caption. Maybe I did something wrong?

I re-used a lot of old parts, it is basically ...

Asus M4A79XTD-EVO AM3 Motherboard - $130.00
AMD 635 Quad 2.9Ghz - $110.00
Kingston 2x2GB DDR3-1333Mhz - $66 x 2 = $130
antec 600 case
8800gt oc2
seasonic 550W
2x 80gb hds raid 0
have about 3 tbs worth of hds to install.

question - the small raid i have now is just for win 7 and apps. i am considering having a raid 1 (2x500gb) for redundancy. is a second, mirrored raid the best way to go? or would it be easier to schedule a nightly drive sync? I ask because I had a really hard time getting win 7 to recognize any raid drivers. i think i had to use 32 bit drivers in the end.

please take a look at the photos and captions, because i am really stumped as to why antec would design the fan mounting as they did. any feedback would be great.

ps - this is my first quad - what are some of the best multi-core apps to run? stuff like fractal imaging, open source quad optimized apps, - anything really.
