Brand new! not a refurb! Checked inside meticulously not a speck of dust on it. It runs perfectly and smoothly. I had to replace the power supply with my own to accommodate my graphics card. CD-ROM not working but it's OK I'm fine with it. soon it will be obsolete anyway.Oops!: They forgot to install heatsink on onboard graphics chips (no worries) fixed myself from old M board b4 recycledWow!: Brand new even the case! Runs above my expectation
