I have the Xon-102 which is the Blue/Gray and yes it is a good case.
I use Biostar 965PT which I said has 2 Case fan connectors but thats becuase I don't need RAID like the S3 supports.
The Xon's use only one connector for the front LED light so in that case...
Your PSU will have 6 connectors sooo....
3 for Case fans
2 for DVD drives
1 for the XION Light on the front.
then you use 1 connector on the mobo for the last case fan.
Yes if you use that Xclio I posted then you will have enough to run it everything.
EDIT: Thanks Nagasama man...he's right. The Single 3-pin fan connector on that board is right above the Black FDD connector. I was looking and I could NOT find it haha. Nice one there man
And yes You will be able to use the cheaper one that I have stated.
