Welcome to the forum kees. I'm not sure if you're looking for a ready computer or are you going to build one. It's also difficult to help without knowing all kind of stuff, like: - what kind of connections you need to the back panel? - what programs are you using? - do you need video playback? How g...

Component recommendations for HTPC, please

I'm starting from point zero (meaning I have nothing yet) and I'm aiming for a tiny, energy efficient, passive cooled build just barely capable for the following: - tiny Linux MediaCenter OS - 7.1 audio via HDMI 1.3 - HD 1080p video - WiFi (Wlan N) - remote control Parts I would like to have recomme...

It should be easy if you have a change to setup water hoses high above your system. Even better if you have a cool place up there which water must pass during it's journey.

Now, I know the plug-and-play WC systems (like that little Corsair thing) don't really cut it, but I've always heard that a good water cooler - particularly with a passive rad - is about as quiet as you can get. No? No. Never has been -- I'd say SPCR enthusiasts' top air-cooled systems have been ch...

the pressure is (and must be) the same inside the case and in the room.. Wrong. If it was, there would be no reason for the air to enter the case. You're right - but when the replacement air enters the case from big intake vents the pressure is soon balanced. Then the chimney causes negative pressu...

Is it possible that the FanMate reduces the voltage under the lowest voltage that keeps the fan rolling? There are two important voltages for each fan model: one that starts them up and the minimum that keeps them rolling. Most fans need at least 8-9V to start and 5-7V to keep rolling. Horizontally ...
