While you probably haven't heard of Mitac, you've definitely heard of Tyan Computer. They are infamous for not only making robust server equipment, but high-end desktop equipment as well, and were one of the first companies to make dual-processor boards for home use. Now, Mitac International will be acquiring Tyan, with a stock trade. Currently, Mitac already holds a 35% share in Tyan, so for them it is not much of a surprise. The companies are not in direct competition, with Mitac doing OEM work and Tyan doing reselling.
The ultimate goal is to increase Tyan's product lines and production volume, enabling them to better compete with other high-end vendors like Intel and SuperMicro.
