Manufacturer Part #: 4U-600
This 4U Server Rackmount Chassis from Ark Technology combines all the protection and features you want in a rackmount chassis (such as Micro ATX, ATX and eATX support and 2 front panel USB 2.0 ports) at a cost that'll keep you well under budget. And with a full 600mm of depth (deeper than the 4U-500), there's enough room in your rack for everything you need.
The 4U-600 drive is equipped with one external and nine internal 3.5" drive bays along with three more external 5.25" bays. It's only 4 units tall, which conserves space while providing plenty of functionality. Built to ATX specs, it's also perfect for data storage, multiple boot or any other RAID application.
At a fraction of the cost of other server cases, the 4U-600 is deeper than 4U-500, can take eATX motherboards and was designed with the network administrator in mind. And the lockable zinc-coated steel door literally brings your network security into the real world.
