Summary: Excellent little home system. I used it to build a NAS server and so far I am very happy with the system. I upgraded the system to max out the memory and I am also using the CD/DVD bay as a 5th HDD. I bought a HDD drive rack and it fit in without much of a hassle.
Summary: I've had this server running in my house for a little over a year and a half now. I got a great holiday combo deal from Newegg back then. I purchased it as a way to consolidate all the files and backups I had scattered over 4 PCs and 5 or six external drives.
Pros: Small size, low power usage, easy access to drives,
Cons: Very tight inside, difficult to install add in card.
Summary: Why buy a NAS or a SAN when you can make your own. I liked the one I bought so much I bought another. Have had zero issues with it. I installed Windows Server 2012 and everything was recognized out of the box.
Pros: Small. Can fit 4 drives and came with the caddies to do so. e-SATA support. ECC support.
Cons: 2TB limit on internal drives. 8GB RAM limit.
Summary: Later the support guy on the phone told me a server is down, so he couldn't enter my case either. But he will make sure to enter my info in a few hours when the system is up.
Pros: I have had the server for a while. No prob with features and usage. I added a HDMI video card and use it as home theater server using XBMC.
Cons: I first tried hp.com's chat help, but microserver is not supported by chat. tried email help, but also not support by email. tried to submit a case myself, but got error "The service or information you requested is not available at this time." The whole hp website was sluggish and annoying to nav...
Summary: This is generally a well built machine for such a small formfactor. You have to sacrifice some ease of installation of expansion cards and memory for the size and airflow. Basically, this is a well thought-out machine.
Pros: This machine is whisper quiet.
Cons: Needs a hot-swappable back-plane and RAID controller that supports it.
Summary: I purchased this unit on Shell-Shocker deal to replace my aging HP Mediasmart server. The CPU is less powerful, but the box overall is more flexible. As Microsoft has unfortunately orphaned Windows Home Server, I am running Server 2012 Essentials on mine.
Pros: Two expansion slots, one can support an HP Remote Access controller card for lights-out management
Cons: Driver support a bit spotty on Server 2012 (e.g., HP has drivers for RAID, but not AHC on the SATA controller, I had to second-source drivers from AMD for that and the VGA drivers on the optional Remote Access Card from Aspeed)
