Inside the Sentey Arvina GS-6400R
Both panels of the Arvina GS-6400R are fastened to the case using black thumbscrews, but you also need to press a latch to release them. In Figure 8, you have an overall look at the inside of the GS-6400R.
The two 80 mm side fans are installed on a bracket that is really easy to be removed, as it features a quick disconnect mechanism. Translation: you don’t need to remove or reconnect any power plug when remove or reinstall this bracket. These side fans glow red when turned on, but the manufacturer didn’t say their technical specifications.
