These ain't no copycat cubes.
For gamers and enthusiasts, the most attractive member of the Mania series is the Socket 939-based Qbic EQ3901. With four colors to choose from, VIA's trusty K8T800 Pro chipset, a pair of 5.25" drive bays, and a beefy 300W power supply, the Qbic EQ3901 could be a great alternative to more established small form factor brands. Read on to find out if it measures up.
The Qbic's spec sheet gives us a good idea of the kinds of features and performance we can expect, but it doesn't come close to conveying what makes it really unique. For that, we need to feast our eyes on the cube itself.
The EQ3901 looks like a cross between a '57 Chevy and a Mini Cooper, which certainly sets it apart from the rest of the small form factor field. Let's have a closer look.

The Qbic we'll be looking at today supports AMD's 939-pin Athlon 64 processors and uses VIA's tried-and-true K8T800 Pro chipset. The K8T800 Pro, complete with its VT8237 south bridge, serves up just about everything an enthusiast-oriented cube should have, including a full-speed HyperTransport link, Serial ATA RAID, and AGP graphics for those who aren't quite ready to make the jump to PCI Express.
Soltek augments the K8T800 Pro's feature set with a little loving from the crab. Realtek's RTL8110S Gigabit Ethernet controller and eight-channel ALC850 codec chip both grace the board. Don't confuse the ALC850 with the ALC880; the latter can handle the higher sampling rates and resolutions required by Intel's new High Definition Audio standard, while the former is simply an eight-channel AC'97 codec.
Normally, I'm not too enthusiastic about PCI-based Gigabit Ethernet chips, but I don't mind the PCI-based RTL8110S on the Qbic. The cube only has a single PCI slot, and apart from its Firewire chip, no other devices are vying for PCI bus bandwidth, so bus contention shouldn't be a problem.
