Htpc aka "Media Center": cheap and *silent*?

It may be me, or the place I live (Italy), but it seems pretty hard to get a build or a prebuilt nettop or a laptop that fits the need.

I need something

• silent
• able to playback all h.264 fullhd content without stuttering, and well (and not loosing the hw acceleration because of softsubs...)
• silent
• not ugly
• silent
• and (possibly) cheap.

I'm going the linux route, therefore i'm moving towards a cpu-based or nvida-integrated solution (i don't think ati hw accelerated playback - or the intel "hd" acceleration - is useable yet).

Ion nettop; it's either

• the Acer Revo (but here it's incredibly pricey and it's hard to find the dualcore version) or
• the Asrock Ion 330, that in the current version is rated "silent" at 26Db. 26. Sounds pretty noisy to me!!! the previous version was even worse. was this product really aimed at htpc market??
• the Dell Zino - i think it's ATI based unfortunately.

Laptop:

• correct me if I'm wrong: sub 600€/$ units are quite loud under full load (because of the tiny fans).
• ULW laptops are indeed quite similar: tiniest fans => high pitched noise and the cpu still lacks power for non hd-accelerated video decoding

Handmade build:

• little money can be saved with underpowered cpus, a low-midrange cpu would help in the case of non-hw-accelerated content
• the cases are quite pricey
• the PSU one has to get ranges between 100/150 €/$ minimum to keep the noise down
• a low-mid build, all included, sums up to over 650 €/$ for a still-looking-ugly-unit, without the blu-ray drive.

Please help. What do you advise on this? ;)

Am I ignoring laptops too much, maybe? Are low-priced Acers that noisy/high pitched under full load?

Solution 1:

In case you go the handmade route, look at

• this tomshardware link
• this thread on a graphics card for an HTPC
• this thread on HTPC PSUs
• this motherboard+cpu thread
• this processor thread
• this link on video encoding performance
• This link on CPU benchmarks (to help aid in a final decision)
• This case
• this thread on HTPCs

Note that water cooling your CPU and/or graphics card (ram maybe even? shrugs) will result in what is essentially a silent system but A: will cost a lot more and B: will be messier.

Solution 2:

For silence, the most important thing is to avoid any fan smaller than 120mm. This applies to all fans in the system. All smaller fans are noisy. The 40mm fans that come on many video cards and motherboard chipsets are particularly bad.

I find a lot of useful info on www.silentpcreview.com. I am not affiliated with that site; I have a homebuilt linux-based HTPC and a homebuilt system that I keep in my bedroom, so silence is important to me.

By the way, 26dB is extremely quiet! It sounds like a high number, but if it really is 26dB, you won't hear it unless you put your ear up against it.
