Rosewill RSV-L4000 Rackmount Case
The front locking cover is the same on all of Rosewill's 4u rackmount cases. The front door provides security for the system so the system can't be shut down or rebooted.
The front door has an air filter across the entire surface that is removable for cleaning. The filter is dense enough to keep the dust out, but porous enough to let air flow through nearly unrestricted.
Here we get our first look with the door open. The RSV-L4000 has two 120mm fans in the front and an additional three 120mm fans in the middle of the case to keep the inner components cool. Behind each front fan are four 3.5" drive sleds. You need to remove the whole fan assembly to access the drives.
The Rosewill 4u chassis ship predrilled for rails, but they are NOT included in the package. Newegg lists a Rosewill 3-section rail kit that is adjustable for length and uses ball bearings for the slides. The kit is $39.99.
The back of the chassis looks like any other steel ATX case on the market. Two 80mm fans exhaust air from the system.
The PSU mount can rotate sides so the power supply can face either direction. Some PSUs have a large fan on one side, but the fan isn't always on the same side.
From the factory, the case ships with rubber feet on the bottom of the case. You'll take these off prior to putting the case in a rack, but the feet keep the case from scratching your desk during the system build.
The handles are a longer than what we find on Supermicro and other rackmount cases. We found a couple reports where the handles were an issue with doors on racks. Most racks are adjustable, so you can maneuver the rails back if needed, but most people wouldn't want to do that on a rack that is already populated with systems.
