- Thread-topic: [SLUG] MythTV hardware advice sought
Here are some pics of my recent HTPC adventure, unfortunately I forgot to get a pic of the thing in its final resting place...
Antec Remote Fusion Black HTPC Case
Antec Signature 650w psu
DFI Lan party JR 9400 T2RS
Intel Q9400 CPU
2x2Gb Patriot 1066Mhz DDR2 ram
2 x 1TB WD Green HDD
Pioneer Sata DVD RW
Scythe mini ninja cooler
Noctua 120 silent case fans
Logitech diNovo mini Bluetooth keyboard
Overall I am happy with the build, the cpu is passively cooled by the new case fans as the cooler sits perfectly along side the fans.
Audio / Video over onboard HDMI.
The unit is whisper quiet, the PSU uses a 80mm fan and was recommended by silentpcreview.com.
Currently running ubuntu 9.10 / mythtv 0.22.
Overall cost was $1700 but you could definitely do it cheaper.

Many audio amps that have hdmi ports don't actually decode the audio on
the hdmi channel, just something to be wary of.

Yeah it's probably overkill though and in my experince video card fans
make loads of noise relative to their size.

should be, My dads TV was (until a few days ago) a P4 3Ghz with no vdpau.

Only major upside to it is reduced disk load as it can commflag it can
do it without writing it to disk again.
Look also at tweaking the file system options so it'll use like 256mb
blocks, its not actually a block size of 256mb but you tell the FS that
it'll have big files on it on average and if your streaming 2 files onto
the one disk it'll help to stop it from getting really fragmented.

I'm fairly finiky about it but it all looks good enough to me.

heh, If your going to do transcoding that's pretty true, again quad core
will get you the performace for the price and thermal more than faster
dual cores ;->

HDD's are pretty silent unless they are super fast to my ear.
A 5400RPM drive makes almost no noise next to the 15Krpm seagate cheetah
I just put into the missus PC ;->
Having the multiple pools will reduce the amount of disk seeking you
need to do and seeks are pretty noisy.
Also you can usually tweak the hdd's noise settings and put them into
quiet mode where I believe they slow down the seeks so they make less noise.

My feeling is that provided the thing isnt actually "loud" a little bit
of noise is ok, you can't hear it anyway when the TV is on ;->

I looked at that, I was going to get one but they were like $240 Vs the
BTW the shintaro can be recovered from having a bowl of stroganoff
dumped into it (If your interested).

I tried to get the IR remote to work, but by the time it got close I was
used to the keyboard ;->
