Why are we so jazzed about this box? Newisys and AMD have managed to fit twin Opteron processors, up to 16 GB of RAM (yes, sixteen gigabytes), an Ultra320 SCSI disk system with 2 drive bays, a CD-ROM drive, a floppy drive, twin Gigabit Ethernet ports, and an integrated systems management card (think web-based Compaq Insight Manager on steroids, running its own dedicated PowerPC embedded Linux machine) all in a 1U rackmount machine. And the thing practically makes no noise and gives off no heat whatsoever.
