Inside the Rosewill RSV-Z2600
Here we get out first look at the inside of the case. Three trays hold hard drives above the motherboard. The two on the left hold one HDD each, and the tray on the right holds two hard drives.
A foam mesh in the front helps to keep the dust build up down inside the case. Three 80mm fans in the front of the case pull cool air into the system. The fans use 4-pin Molex connectors but not 3-pin or 4-pin motherboard fan headers.
The right side HDD holder can flip to the side. This allows more room for the power supply and power supply cables. You can also remove drive cages that are not needed.
We're using an ASRock C2550D4I motherboard that has an Intel Atom C2550 quad-core processor for this build. The C2550D4I also works for NAS system builds since it has twelve SATA ports, four DDR3 slots, a PCIe slot, dual gigabit Ethernet ports, and an IPMI port for management with iKVM support.
We had a spare power supply to use for this build, but the fan configuration means we can't put another rackmount case on top of the RSV-Z2600 and expect the power supply to survive for too long since it will block air flow.
