I installed Windows Home Server 2011 on this rackmount unit to backup my PCs, share documents, and stream media. This unit has the performance to handle these tasks. The RAID1 setup will assure continued operation if one of the 1Tb hard drives fail.
You should be aware that the unit does not have an optical drive and an external USB drive is needed to install the OS. For Windows installations little to no change to the BIOS is needed. The unit's fans are very loud out of the box. The server comes with basic instructions and no in-depth info on the unit's features. However, it gets the best-bang-for-your-buck award of the various rackmount servers I researched.
