Summary: System was running for two weeks, then died. Working to get a replacement now. System is very sluggish when installing Windows for the first time. The install goes quickly once you have the chip-set drivers installed. **Update** (Oct. 13th 2012) I sent the unit back to Zotac which they replaced. The new unit has been working for a while now. Windows 7 with 4G RAM, a little sluggish at times but I'm happy with how loaded the system is.
