Outfitted for corporate cubicles, the IBM ThinkCentre S50 may also be just the thing for small offices with an eye toward data management and PC usability. The series offers a range of Intel Celeron D and Pentium 4 processors inside a crafty small-form-factor case that's laughably easy to access. Our test system's performance was hampered by an older Pentium 4 processor that could not take advantage of the system's newer Intel 865G chipset, but choosing a compatible CPU should improve the ThinkCentre S50's efficiency. (Hint: the newer chips have a three-digit model number, as in Pentium 4 540.) This system's true claim to fame is its IT-management software, which includes Rapid Restore for preserving data and applications in case of system failure, and Access IBM, a configuration utility. Combined with IBM's copious warranty services, the ThinkCentre S50 is one of the finest business-minded PCs to pass through our Labs.
