Turning the pages of this magazine makes more
noise than this year's Ultimate Linux Box does.
The RME sound card uses this handy Multiface box
to offer standard connections for digital and analog
audio, along with MIDI. Because RME uses the same
interface for its PCMCIA cards, you can take the
same Multiface along to use with your laptop for
remote sessions (photo: Don Cameron).
The Ultimate Linux Box has three separate cooling
loops: one for the power supply and two that
each handle two CPUs. We carefully monitored CPU
temperatures with lm_sensors. CPU temperature rises
a little before the water in the “up” tube warms up
enough to start convection (photo: Don Cameron).
With the heatsink fins milled flat, we were able
to attach custom waterblocks for fanless cooling
of the modified power supply, shown here mounted on
a temporary rack for testing. The waterblocks and
the custom Y-connectors are anodized blue to match
the Zalman parts (photo: Don Marti).
The Ultimate Linux Box boots from a CompactFlash
card with an ATA adapter. Pull the card out to make
an easy backup. 256MB is plenty of space for /boot,
and the rest of the storage is at the other end of
a long fiber optic cable. Going back to a noisy PC
after using this machine was sure hard on the ears (photo: Don Cameron).
