XSeries

Helping orphans the way you would do it
The IBM xSeries computers form a sub-brand of International Business Machines (IBM)'s eServer brand servers (the other eServer sub-brands having the names iSeries, pSeries, and zSeries).

Formerly known as NetFinity servers, the xSeries are distinguished by being based on off-the-shelf Intel CPUss; IBM positions them as their "low end" offering.
