Re: A silent computer as a multi-purpose home server / ASUS Terminator C3

I got the ASUS Terminator C3 last week! Here is my summary, as promised. 

(Just to remind everyone, Terminator C3 is a small barebone with a VIA
C3 processor, CD-ROM and floppy drives, which accepts DDR memory, and
costs only 115 USD.)

First of all, it is really much smaller than I thought it was going to be. :-) 

There are two fans: one cool the C3 processor and another is a 90 or
92 mm exhaust fan. The fans are very noisy! Luckily, both fans are
connected with a standard 3-pin connector right to the motherboard, so
used a Zalman MC-1 (with 5V connector) for the exhaust fan, and Zalman
Fan Mate 2 for the cpu-fan. BIOS had only one option for fan controls:
"Q-FAN Function: [Enable/Disable]", and I didn't find it quiet enough,
although it was controlling both fans.

The barebone came with a thick printed documentation, although the
docs do not mention much about the specifications of the case,
specifically, of what is the size of the exhaust fan is (read "how
could I know for sure if I need to buy a 90 or 92 mm exhaust fan
replacement to improve acoustics/air circulation?"). Moreover, they
seem to have supplied a different BIOS that does not have any
additional Q-FAN controls that are outlined in the documentation (I'd
love to have those advertised controls!).

I was disappointed, although not surprised, that the system didn't
came with a spare IDE cable for the hard-drive. I had to install the
HDD on the same cable as the CD-ROM, so the HDD interface speed
appears to be limited, according to OpenBSD (it is still on an 80-wire
cable, though).

The system seemed to be very fast in the console, but as soon as I've
written "startkde" in the terminal, I realised that the system is
terribly slow! Processor idle was around 5% and it was starting very
slowly (first start was more than a minute). Anyhow, what was I
expecting? :-)

Overall, the system appears to be all right and rather quiet (after my
modifications). Certainly, if they have had packaged the interface
cables for the hard-drive, it would have been very nice. In addition,
I'd prefer the possibility of installing an 80mm fan instead of the
supplied fan of both unpopular and unknown size (90 or 92mm, the
supplied exhaust fan that is).

My only problem now is the high-pitched whine of the otherwise silent
Hitachi hard-drive... I'm thinking of replacing it with a 2.5" 4200rpm
notebook-style drive (Fujitsu MHT2040AT).

2.5" drives have different power connectors, don't they? Would it be
easier to buy some USB 2.0 external enclosure for 20 USD from
newegg.com and put the drive into the enclosure? Will it work with
OpenBSD and my BIOS? (If it's not going to work with BIOS, I assume
that creating a special boot floppy or CD should solve the problem,
right?) Is performance going to suffer greatly with the introduction
of a USB 2.0 link before the drive? The idea of external drive
otherwise sounds pleasing, as I would always be able to switch the
whole system to a different hardware very easily.

Here comes the dmesg:
