I've got a HP N40L Microserver at the moment. The stock unit is quite noisy, most of the noise coming from the PSU.
The Scythe Slipstream fan mod mentioned in the SPCR article is easy to do and works well. There's a torx key included inside the server's case door that you can use for removing the fan.
It's worth bearing in mind that not all Picopsu models will fit in the HP N40L Microserver. The Picopsu 160-XT power supply, which has four capacitors, is too tall and won't slide underneath the hard drive bay.http://www.itx-warehouse.co.uk/Product. ... uctID=1310
The 120 watt Picopsu, which has two capacitors, is smaller. I've got one on order to try instead.http://www.itx-warehouse.co.uk/Product. ... ductID=533
I'm going to use a Samsung 830 128gb SSD for the operating system. One of these Icy Dock EZConvert MB882SP-1S-2B 2.5" to 3.5" SATA SSD / Hard Drive Converter lets you put an SSD in one of the main drive bays.http://www.icydock.com/goods.php?id=77
I was originally building this server with stock parts for someone else. It was going to be in a garage as their home server. It was to have the 250gb Seagate Barracuda 7200.12 drive for the Windows Home Server 2011 operating system and then a pair of 3TB Seagate Barracuda 7200.12 drives in Raid 1 for data storage. It was all working fine and seemed very stable, no problems using the 3TB hard drives either. They show up in the BIOS and you initialise them as GPT partition through Windows Disk Management to use their full capacity.
Then the mains power lead was accidentally unplugged whilst the server was running, as though there had been a power cut...
You wouldn't think an unscheduled shutdown would be a big deal but when the server was rebooted it had lost the raid array in the BIOS, all the data drive shares had vanished in Windows Home Server 2011 and the two 3TB drives which had used GPT file partitions were showing as no longer initialised also. The main 250gb operating system drive with its MBR partition was fine and still working normally
In a way it was good that it happened whilst I was still setting it up. If all the data had been lost from both of the Raid drives when it was in use that would have been much worse. It would have been connected to a UPS for normal use, reducing the risk from a power cut. Even so, having the potential for losing everything like that with the 3TB drives was too much of a risk. I ended up using a Synology DS213+ NAS box for the garage install instead, leaving me with this HP Microserver. The plan now is to get some 2TB drives for it (using MBR partitions), AHCI BIOS mode, not have the drives mirrored and instead use a scheduled robocopy to back one drive up onto the other drive.
