The HP MicroServer is a great little unit to use for development/testing purposes. I have one on my workbench with 8gb of memory with Hyper-V. It allows to test out new versions of Workstation software, WHS, SBS and Multipoint.

Note that the HP MicroServer comes with built-in Raid-0/Raid-1 support.

The server has slots for two half-size cards.

The inner slot (the one closer to the on-board NIC) can only be used for the HP MicroServer Remote Access Card (RAC), which is sort of like a basic version of the HP ILO card for servers, and provides remote (virtual) KVM.

• Check out Philip Elder’s post on installing the HP MicroServer Remote Access Card
• Check out the HP support document to reset the password on the RAC

The second slot (the one closer to the outer edge of the box) can be used for other purposes, such as a low profile PCIe X16 Graphic Add-in card.
