HP Z220 Workstation with Quad Core Xeon processor and 500GB HDD

Solid entry-level workstation with plenty of upgrade headroom. Currently equipped with an Intel Xeon E3-1225 v2 (3.2 GHz base / 3.6 GHz Turbo) with 4 cores and 4 threads and 8GB DDR3 RAM (upgradeable to 32GB ECC/non-ECC). The platform supports CPU upgrades up to the Xeon E3-1290 v2 (3.7 GHz base / 4.1 GHz Turbo) or Core i7-3770K (3.4 GHz base / 3.9 GHz Turbo) — both quad-core, 8-thread chips — making it an easy way to squeeze more performance down the road without spending extra now. Seagate 500GB SATA drive included with a fresh installation of Linux Mint Cinnamon. Alternatively, any desktop version of Windows can be installed upon request. $100 OBO
