Let me start by saying the STGSivir All-in-One desktop is a visual treat right out of the box. The RGB keyboard, mouse, and mouse pad create a fun gaming vibe even if you're just doing spreadsheets. Setup was a breeze - I had it running in under 10 minutes.

The 21.5" FHD display delivers crisp visuals perfect for my photo editing work. Colors pop nicely, though professional designers might want more color accuracy. The built-in webcam is surprisingly decent for Zoom calls - no more hunting for that external cam!

Performance-wise, the i5 processor handles everyday tasks smoothly. I regularly have 15+ Chrome tabs open while streaming music with no lag. The 16GB RAM makes multitasking feel effortless compared to my old laptop.

Now for the quirks: That Windows 11 limitation is real. After multiple failed update attempts (and some colorful language), I confirmed this model won't upgrade. Also experienced occasional game lag despite my fiber internet - probably not ideal for hardcore gamers.

The RGB mouse staying on after shutdown is... odd? It's like having a nightlight I didn't ask for. And while tech support gets rave reviews, you shouldn't need them immediately.

Bottom line: For $600-$700 range, it's solid value if you're okay with Windows 10 until 2025 and don't need heavy gaming performance. Just maybe keep the receipt handy - quality control seems hit or miss based on reviews.
