Lenovo ThinkSystem ST50
Lenovo's entry single-socket tower server (machine types 7Y48 / 7Y49) for one Intel Xeon E-2100 or E-2200 processor (or Core i3, Pentium or Celeron), with four UDIMM slots (up to 64 GB), up to four 3.5-inch non-hot-swap drives and three PCIe 3.0 slots. Quiet and small enough to sit beside a desk, it is aimed at small businesses, home offices, retail, education and branch offices.
