The monitor is the standard Tandy VGA monitor of the system's era. The styling on the speakers feel newer than the RSX's 1991 launch, they're more what I'd expect from the mid to late 90s.
You had to upgrade the VGA chip's BIOS to use Win 95 on it:
> The ACUMOS VGA graphics can be software-updated with Cirrus Logic BIOS (via MS-DOS driver) to allow VESA/SVGA to function in Windows 95, as the Windows 3.xx Tandy VGA drivers are insufficient for Windows 95.

I think the background image is probably authentic, it has the feel of a mid-late 90s digital camera picture. It reads to me as the desk of someone who is trying to keep that system alive long past its prime years. Which were arguably over before they started, given 486 systems had been available for a bit when this launched. We end up with an early 90s system with a handful of mid-late 90s peripherals.
The bigger problem to me is this sounds like MIDI played back on a sound card with FM synthesis. The 1000 RSX had the poorly supported Tandy 3 tones + DAC sound hardware. You could install an AdLib, Sound Blaster, or other card to give it MIDI FM synth capability, but the base system can't do it. Alas, we can't see the back to see if it has such an upgrade...
When I was a kid, I was using Windows 95 for a while when Me was already a thing - newer versions could technically run, but the experience wasn't great on that hardware. You could even still find Windows 3.11 computers at my school at the time. Computers don't go die at the exact moment a successor becomes available on the market.
