This is an amazing laptop for this price (3300 mexican pesos, this is around 235 dollars). Good sound, webcam, keyboard, it is very lightweight and near silent because is fanless. Scree...

Re: A fanless home file server

nice build! expecially the home-made case. :)
I have the same intel mobo, it is in a small htpc I tried to build but is too slow/weak for that purpose. I will try to reuse it for a file/music server.

Re: quiet low-power mini-itx i3 2100t build

yes leem, I tweaked all what the mobo let me change in bios for low power consumption. For example I undervolted a bit the ram (not too much, only from1.5v to 1.4v. I will try to push down the voltage a bit more). It isn't possible to undervolt the CPU, but the i3 is very efficient itself at stock v...

Re: mini-ITX LGA1155: efficient PSUs? PicoPSU+brick? or othe

my i3 LGA1155 mini-itx rig is powered by a PicoPSU 90 + a 72w 12v power brick. [ http://www.silentpcreview.com/forums/viewtopic.php?f=14&t=62743 ] Seems to me a pretty efficient combination.

I can't see a point in a completely passive build, in a silence perspective. As others has stated, a single low-revolution fan is inaudible. So, what's the benefit to run a pc passively?

sure, it will work!

but 120w is overkill for a PICO-90. You can find cheaper power bricks rated at 90w or 100w. For example, multi-plug/voltages power supplies for laptops.

the "e" processors are hard to find, in my experience. Maybe are slightly better, but "regular" athlons if undervolted can perform also very well in power consumption.

pico 120 (if not defective) can feed your rig. I have a pico 120-wi with an Athlon II x2 system, and works perfectly.

Have you checked the power brick instead? Maybe this is the responsible.

hi kubunteando, your rig actually has a good power consumption because you have a dedicated graphic card. 42w is not bad at all.
