ZDnet reviews X4450
ZDnet wrote a nice review about the Sun Fire X4450:
For raw power this is the gutsiest server we have seen. The benchmark results are the best we have seen in high end servers — particularly the Sungard score — although we cannot claim to have tested such a machine with specs quite like this before.
But the best part of the article is a different one:
Too often we look inside a server and think, "what a mess!" Strange air flow and cable routing is common — but not so with the X4450. There is hardly a cable in sight and airflow is straight as an arrow from front to back.
