tower placement

Hello - I am using gateway desktop PC as my server - my room is carpet over concrete slab and the tower is currently directly on the carpet.  Is it advisable to place it on something - pucks and/or cones?  I am only using discs (cds and blu rays) in the tower when I rip them - all the playback is from the hard drive.  thank you
The issue with carpet and padding is the ability of the speaker to move back and forth in response to the force from the woofers. As a result you normally want to have spikes that go through the carpet, and you want them as far out as possible. 

With some speakers, which have spike holes directly under the cabinet, it's too narrow a footprint for safety and you will need outriggers.
thanks Erik but sorry  -  I meant the desktop computer tower - not the speakers -
