Zotac has a lot of experience when it comes to building mini-PCs, but the Zotac ZBox Sphere might be its most visually captivating and stylish yet. As its name implies, the ZBox Sphere is constructed to resemble an orb, but you can see that it has a flat base and back when you view it from the side. Indeed, the ZBox Spheres shape is so unconventional that it met with a number of puzzled when we pulled it out of the box, and many people didnt realise it was a PC at first glance.
One neat feature of the Sphere is a blue strip around its circumference that lights up when the systems powered on. You can even change its behaviour in the Spheres BIOS so that it pulsates, stays lit or gradually orbits around the unit. You can also turn the light off if you find it too distracting.
While the chassis is pretty compact at just 154x154x161mm, you might find its difficult to fit ZBox Sphere within the shelves of your TV stand due to its height. This is worth keeping in mind if youre planning to use the system as a living room PC or HTPC. The power button is also tucked away at the back of the system, which could prove annoying if its tucked away in a hard to reach place, but you can wake the PC from USB and your network.
FLEXI-SPECS
The Zotac ZBox Sphere comes in two distinct versions: the OI520 (around £270), which comes with no memory or hard disk, and the OI520 Plus (£370) which includes 4GB SODIMM DDR3L and a 500GB HDD. Both models include an Intel Core i5 4200U 1.6GHz dual-core processor that supports Intel Turbo Boost up to 2.6GHz. Neither version comes with a Windows licence, so youll need to buy your own copy, or install a free operating system such as Linux. Weve reviewed the OI520 Plus.
Both Windows 7 and Windows 8/8.1 are officially supported by Zotac, and we opted to install Windows 8.1 on our review system. Once youve installed an operating system you will, of course, have to install all the necessary drivers manually. Zotac provides drivers on a USB flash drive, which is convenient because the Zotac does not include an optical drive. Youll need to install the drivers to use the ZBox Spheres built-in Wi-Fi adaptor.
We subjected the Zbox Sphere to our application benchmarks and were pleased to see that it scored 51 overall, as this is a few points higher than wed expect from an Intel Core i5-4200U-based PC. This score shows that the ZBox Sphere is powerful enough for most general-purpose tasks, such as browsing the web, running productivity software and play movies. The ZBox Sphere even played our 4K resolution test files without a hitch.
Sadly, the processors built-in HD 4400 graphics processor isnt suited to 3D gaming, and the ZBox Sphere only managed to produce an average frame rate of 19.5fps in our Dirt Showdown benchmark at a resolution of 1,280×720 with 4x anti-aliasing and graphics quality set to High. You should have no problem with casual games, though, and we played Minecraft at a decently smooth average frame rate of 51fps.
At the back of the system youll find display outputs for HDMI and DisplayPort, audio connections for a microphone and headphone, four USB3 ports, two USB2 ports and a 4-in-1 card reader with support for MMC, SD, SDHC and SDXC cards. Theres also a Gigabit Ethernet port, a built-in 802.11ac adaptor and Bluetooth 4.0 support, so you wont have a problem connecting to networks or attaching wireless peripherals. On one side of the Sphere is an additional USB2 port and a Kensington lock.
HOLLOW EARTH
Its easy to open the Zotac ZBox Sphere, you simply unscrew the top of it. On the motherboard, youll find two slots for DDR3L SO-DIMM memory, with one slot of the ZBox Sphere Plus already occupied by a 4GB 1,600MHz module. Theres also a SATA3 port thats connected to a 2½in 500GB hard disk, and an mSATA port to which you can connect an SSD.
We found the Zotac ZBox Sphere OI520 Plus makes for a stylish media centre PC. The processor will handle most home PC tasks and it even outperformed more expensive compact PCs, such as the Best Buy-winning Scan 3XS NUC N16, which scored 48 overall in our benchmarks. Its just a shame the ZBox Sphere only allows for basic gaming. The Scan system proved more capable in our Dirt Showdown tests and has a better balance between price, performance, features and size.
Otherwise, the ZBox Sphere OI520 is a good choice if youre taken by the unique design and dont want to spend a lot on a PC. It runs almost silently, generates very little heat and is impressively well put together. However, wed probably go for the cheaper non-Plus model so that we can specify our own storage and memory capacity.
