Acer Chasis has two screws at the back, which you should open. After removing the screws press the Black T-Shaped button down and pull the side lid backwards to open the chasis as marked/ shown below: -

Viewing the back of the computer, there are two screws to remove on the right side panel, at the rear.

One close to the top, one close to the bottom.

Make sure the screws are going through the side panel itself.

After you remove them you pull back on the side cover with one hand, holding onto the computer tower with the other hand.

Sometimes the side cover is tough to pull back.
(Be SURE the computer is unplugged from power)

Would appreciate hearing the outcome of this.

You have done half the work toward the solution by removing the thumbscrews. The other half involves sliding a spring-loaded lever above the lower thumbscrew toward the bottom of the case. While the lever is slid toward the case bottom, push on the side panel in the same direction as the screws, i.e. toward the rear of the case. The side panel should slide just slightly, allowing you to then lift it off to access the inside. Note that when replacing the side panel, follow the above steps in reverse order.

When replacing the side panel, note that if the panel is not correctly replaced, the thumbscrews will not be able to be installed as the lock lever will not be set properly.
