2-12-2015 After updating some packages, I rebooted for the first time after a long time. I thought it would help with cleaning up unused kernels on the boot partition. The box apparently hangs on boot, but no keyboard/monitor are connected so this can still be anything. After connecting some peripherals, nothing happened. Upon trying to reboot the power LED stays on and doesn't respond to pressing (and holding) the power button. Removing and reinserting the power cable is the final straw: now nothing happens, even the power LED stays off.
3-12-2015 In a last attempt to find the culprit, I disassembled the box and plugged in old PSU. Upon connecting power and switching the PSU on, it's fan twitches, but does not start spinning normally. Pressing the power button on the motherboard has no visible effect. The motherboard has probably died.
Building a replacement was already planned, but now has to be rushed unfortunately, so these parts were ordered:
Additionally, I will re-use the drives (80GB + 3TB) and a Samsung 840 SSD (128GB) that I have lying around.
12-12-2015 After assembeling the parts and just popping in the hard drives the system boots normally, although getting the secondary drive to work this requires fixing its entry in /etc/fstab.
The ethernet adapter is not working, which makes sense, because it is a different on-board adapter.

13-12-2015 Of course, since the on-board sound card also changed, its drivers also needs to be reconfigured. I plugged the speakers into the lime port, I just want to use 2 channel sound.

The case and fans were picked for being very silent. Unfortunately, they are still quite loud at the moment. I did have the sense to pick a case with PWM fans, so I need to configure those.
This article describes how to set it up.
sudo apt-get install lm-sensors fancontrol
With the result:
#----cut here---- # Chip drivers coretemp nct6775 #----cut here----
sensorsgives output. I see coretemp around 30 C and RPMs for fan1, fan2, fan5.
Found the following devices: hwmon0/device is coretemp hwmon1 is nct6776 Found the following PWM controls: hwmon1/pwm2 current value: 165 hwmon1/pwm3 current value: 165 respond to changes, pwm1 doesn't. Probably the two chassis fans.
I have a Noctua NH-L9i CPU fan so I could use the Low-Noise adapter, but lets first try PWM.
Fan2 seems to be the CPU fan, because the fan speed corresponds with the max speed of the Noctua NH-L9i. During pwmconfig I found out that setting the speed below 2000 RPM will greatly reduce the sound production. This means the low-noise adapter would definitely help. The CPU fan is hwmon1/fan2_input and is controlled by pwm hwmon1/pwm2.
After configuring both fans with pwmconfig, I start fancontrol service:
sudo service fancontrol start and the noise dropped significantly!
The front fan (I think, I can't really hear it that well) is still quite noisy. It doesn't respond to configuring by pwmconfig, for some reason. I might just turn it off. The state after configuring:
15-12-2015 Added the low noise adapter to the front fan. Running
The noise production is now is very low.
I've also added two extra drives (an SSD and an old 1,5TB HDD) that need to be configured. Running
sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL gives:
NAME FSTYPE SIZE MOUNTPOINT LABEL sda 2.7T `-sda1 ext4 2.7T /mnt/disk3t sdb 74.5G |-sdb1 ext2 243M /boot |-sdb2 1K `-sdb5 LVM2_member 74.3G |-broek-root (dm-0) ext4 71.8G / `-broek-swap_1 (dm-1) swap 2.5G [SWAP] sdc 1.4T `-sdc1 ext3 1.4T OldDrive sdd 119.2G |-sdd1 ext4 119G `-sdd3 vfat 249M EFI
The filesystem sizes give away which drives are which and even the label of one of the drives is still intact. For the moment I mount them manually:
sudo mount /dev/sdc1 /mnt/disk1500g sudo mount /dev/sdd1 /mnt/diskSsdTemp
Both seem to work, so I just added them to the fstab and configured the 1,5TB drive as an export via Webmin.
At this moment only the USB device Rekelbox doesn't work anymore. I thought it might need an update of the USB drivers, not unlike the audio and network drivers before. The initPort.sh script fails with
stty: /dev/ttyUSB0: Inappropriate ioctl for device. Trying to find a solution gives many hits, non of which seem appropriate for my case. Trying a USB flash drive works fine, so I don't think it's the USB drivers.
After searching messageboards for a long time, I just tried rebooting with the USB device plugged in: it started working immediately!
