Well about the fan on the side im using two of these
and they are fantastic, they have two included fan controllers, and are only $4.99! I'm not sure if they have red ones or not though. Iv got mine set really low so they don't hum but i will be getting this
and I am hoping it will fix the humming problem.
You can either use the fan controller that you put in a PCI slot in the back, or you can use one that you put in a 3.5" drive bay.
For making your case go higher im using this
These feet are actually for illumination but they are quite high, so i think these may serve the purpose your wanting. As you can see in the pictures below you don't have to use the LEDs. These feet also reduce vibration noise since there is foam in between the feet and the case.
