That case is like 23" high, right? How high is the bottom of your desk? How much room do you have to lift up the case?
I would get something hard under the case itself... even a 1x8 or 1x10 shelf from home Depot or something would do nicely. Get it off of that carpet.
If you want to put some larger feet on.. MNPC makes some great ones in various heights.... http://mnpctech.com/pc-computer-stereo-desktop-case-feet/
. Bill Owens.. the owner of MNPCtech.. stands behind his stuff too. Awesome customer service.
I picked this up at Home Depot.. and it works great for Towers... but it would be too tall to fit under your desk as is... but just the bottom shelf would do you, and you can buy them separately.Edited by cgipson1 - 4/1/14 at 8:13pm
