Can you please give few more details.
Chassis 5520SC is a workstation, which supports NHM processor based machine.
5300 is the previous generation processor and are you trying to put this processor in 5520SC machine which has NHM supported motherboard.,
Then it wont support.
Let me know if i can be of any assistance,
Actually, i am sure that you know that there is a tested list of compatible intel and non-intel chassis.
Well regarding the questoin whether the SC5300 will work fine with your board, i will need to check this for you and get back to you soon.
I will assume that the fans may not be regulated properly or it may even be that the board wont power up due to power supply issues. Let me check it for you.

All the best,
wont work for at least three reasons.
1. The Front Pannel connection on the 5300 is a 32pin connection. te SC uses a 22 pin
2. the SC requirest 2 x 8pin CPU Power connection. the PSUs from the 5300 series only provide one.
3. the Mounting holes on the chassis standoffs wouln't match that of the SC.
there may be other reasons too.
