Opening Case?

Hello,

I've had a Bolt X for about 8 months. I have realized how dusty it must be and so I moved it to a good place to remove the dust via one of the canned air devices. However, I'm not sure how to open it. I found on the top that there was what looks similar to an AC filter which I pulled out and sprayed with the air to get rid of the dust. I also sprayed on the outside in some of the fans but I'm sure I need to spray inside some as well to completely get rid of the dust.

Just in case it helps, here's my full configuration from when I ordered it.
