Enclosure, 2U-rack case

By: Sander Sassen

All we then needed was a 2U-rack case, a CDROM and floppy and we could start with putting things together. The CDROM and floppy were the least of our worries as weíll only be using them a couple of times to install the OS, maybe do some additional software upgrades or install 3rd party software, but thatís it. We opted for a Mitsumi 48x speed CDROM and a Mitsumi 3.5" 1.44MB floppy drive, simply because they are affordable and offer a good price/performance ratio. The 2U-rack case however took a little more effort as we wanted a well laid-out design with proper airflow and room for all of our components.

Mitsumi CDROM and Floppy

Weíve looked at a large number of rack cases but really wanted something that had drive bays in the front with cooling fans behind them so we could easily replace a defective WD1200JB if needed and have sufficient air flow over all of the disks. We decided on going with the Chenbro RM22100 which is a 2U-rack case with four sliding harddisk brackets in the front and room for a full size CDROM and floppy. It also has a 300-watts powersupply and an internal layout that is well thought out and doesnít intervene with proper system air flow.

Finished Server Cables

Naturally the Chenbro case featured a backplate for U160 SCSI disks which was of no use to us; instead we used normal 80-conductor IDE-cables to hook the disks up to the onboard Promise RAID. If the disks ever have to be replaced we just need to remove the serverís top cover and unplug the defective disk, slide it out, and install the new disk. Maybe a little more work than a true hot-swap SCSI disk, but no more than a couple of minutes, at least we donít need to take the server offline or disassemble it to remove a disk, which is a big advantage.
