Input on this upgrade

[DKYang]

Ok, so I'm upgrading one and using the leftover parts on another system with some older parts that may work. This is where I need your input.

My current main build is:
Intel Core 2 Duo E6750
GIGABYTE GA-P35-DS3P
8800 GTS 320MB
4 GB of DDR2 RAM
500 GB HDD
Corsiar 520HX

I plan to replace the CPU with a Q9400, possibly OC it in the future whenever I feel like it, and the case which is the Raidmax Smilodon Extreme. I want to replace the case with a quite one or one that isn't too loud. This current case is great, but 4 fans was louder than I thought(I was a newb back then). I'm looking for a quieter one that will do a good job. Anyone have any suggestions on a good case? Right now I'm looking at the COOLER MASTER Mystique.

Now, I want to take the E6750 and case to build the other system, but I need a new MOBO and RAM. Here are the parts that I plan to use for the other system.

C2D E6750
GIGABYTE GA-G31M-ES2L
2 GB of DDR2 RAM
7600GT video card
XCLIO XClio 450BL 450W

The other parts not mentioned isn't really important since this system will be used for basic stuff like internet, paint, and some games(not intensive games, something like "learn how to type" games and etc).

I would like your input on the MOBO and PSU that I have chosen. Will the second system run fine? I don't want to spend too much money on the second system.

Thanks for taking your time.

if you dont do a lot a video editing or alot of multi tasking i would recommend getting an e8400 or e8500 and just overclocking

I recommend this case since A) I have the older version and it was damn quiet and B) it was made to be a quiet case:
$120 - Antec P182 ATX Case

The mobo should be ok. However the PSU is ehh. Not too good under proper testing:

So it is not a long term solution according to the above.

I do a lot of multitasking and encoding which is why I picked the Q9400. Not trying to sound rude, but I wasn't really asking input on the new CPU. Sorry if the way I worded it sounded like it.

The PSU you selected isn't great and is deactivated at the Egg.

I'd suggest this one: Corsair 400CX - $50 ($10 rebate)
