Zotac ZBox Sphere Oi520 Series review


Zotac thinks outside the box with a spherical mini PC

Smart looking device ; Solid performer ; Plenty of ports ; Nicely priced

Fragile build quality ; Slight lid design issue ; Not exactly a powerhouse

Scores in depth Today, we live in a post-modern, multi-cultural world where traditional norms have been turned upside down. Half-Cantonese, with an Italian name and heavy Welsh accent? Unlikely to even turn heads. So what's the problem when something...

Zotac ZBOX Sphere OI520 review


Is Zotac's distinctive Zbox Sphere mini-PC a well-rounded computing experience or just a load of old balls?

Unique design Whisper quiet Easy to upgrade

Not very gamey Pricey compared to other options

The performance isn’t out of this world, but Zotac’s globular take on the mini PC is still a spherical spectacle
