This was my home server untel December 2012, an Intel Atom in a barebone case. I was slowly reaching kraftwerk's limits (especially the 6GB hard disk was far too small), and since kraftwerk was also becoming rather unstable I decided to buy a replacement, which turned out to be this box. It's now serving derf.homelinux.org and acting as shell server for me and a few more people.

Initially it only had one 120GB disk, but after my Thinkpad died in 2009 I installed its 250GB disk to be used for backups.

In 2010 (roughly two weeks before reaching 1 year uptime ;-) ) the chipset fan died; I replaced it with a larger one hanging over the whole mainboard. Now the whole box is much cooler and also more silent.

The SMART values of the old Thinkpad disk became problematic in 2011, so it was again replaced, this time by a 500GB 3.5" one.

Services:

  • Mail
  • VPN
  • Website

As of 2012-12-21 it was out of service. Yet another hard disk started making problems, this time the one holding the system partition.

It's used as a backup host with an externel USB hard disk now.

It was originally manufactured by Medion (MD8080XL). However, since pre-built PCs usually suck, it's got some changes since then:

  • In 2006, I intstalled Debian testing (dualboot with the Windows XP)
  • Originally saviour contained 512MB RAM, which was first upgraded to 1536MB and then again to 3072MB.
  • The original video card (ATI Radeon 9800XL, two VGA ports) died because of heat, so it was replaced by an ATI Radeon 9600 (one VGA and one DVI port \o/) with some Zalman (can't remember the exact product number) cooler. This got replaced in 2009 by an nVidia card (finally, working 3D on linux again!), which died in 2010. So now the machine's back to the old (and still working) Radeon 9600.
  • I removed a part of the case next to the video card and replaced it with a thinner case taken from an old laptop. It has tiny holes in it, so it should keep the video card cool.
  • I also removed the TV/Modem combo card. I rarely watch TV, don't need a modem here, and the card's not even capable of DVB-anything. Plus, it consumed energy and blocked the video card's air flow.
  • Most of the front panel (plastic) was removed. It used to carry a 120mm fan right in front of the hard disks, since saviour contained 4 HDDs (despite theoretically only having space for 2). As saviour is only used for gaming now, all but one HDDs got removed and I replaced the 120mm fan by a less noisy 80mm one.

I used to have a PCI card for PATA/SATA disks installed because the mainboard doesn't support SATA, but it only caused problems (SATA only works if PATA is connected, and even then not always), so I threw it out and put the one SATA disk in saviour into an external case.

In spring 2012, saviour finally got replaced by carbon as my primary workstation. It is now used as a backup host with an LV on sd[a-d].

Netbook for everyday use, bought after my Thinkpad T41 broke down (damn you, Flexing problem). I used it as workstation for about a year (with external monitor/keyboard/mouse/sound), but all in all it was too slow and also too tedious to dis- and reconnect all the cables everytime I went somewhere.

Got replaced by illusion in spring 2013, now stored as fallback notebook.

Since kraftwerk was getting old and I needed a useful laptop for traveling etc., I bought nemesis. It's really nice, has a slim case and can (thanks to thinkpad-acpi) even be used for blinkenlights and stuff. However, nemesis contained used parts, which proved to be fatal because of the "Flexing" problem of the 4x series. So it got replaced by a T41, which lasted almost a year, but then also broke down. As I was quite annoyed by Thinkpads by then, I decided to get some cheap netbook instead, which turned out to be descent and is (so far) working fine.

kraftwerk (used to be "gamma") is a Toshiba Satellite 2670DVD, bought in the Spring of 2000.

It was my very first notebook and used to run Windows 98 SE. In 2006 that OS got replaced by OpenBSD, which was again replaced by Debian testing late 2007. From 2006 to 2008 I used it as a home server, until it got replaced by aneurysm.

I didn't really use it afterwards, however kraftwerk ran the intercensor system on a few events.
