server cabinet noise reducing

Thanks to @Rand__ for his help purchasing a solid Supermicro SC216 (2U) with a super quiet PWS-920P-SQ. I didn't have so much space for another 3U or 4U case in my IKEA home rack. Therefore I was looking for a 2U unit only, fully aware of the problems coming with it in a home office environment...

UPDATE: ALL CABINETS ARE NOW SOLD. Located in Palo Alto, CA. Delivery available in SF Bay and surrounding area for extra $50-150 depending on distance / travel time, etc. These are the deep versions suitable for full length servers not the shallow studio versions just for short length servers...
