I've done a few 2-in-1 builds, and the are quite fun; certainly worth the challenge. Typically I just use foam mounting tape to attach a VIA motherboard with PICO and flash storage to the door, with an internal KVM switch. There are a number of cases that support a second EPIA system already, but I'...

A good 350W PS is more than enough for that load. The most demanding element is the 2600, and that isn't bad.

I would do some more research on consumption on the 5V rail. It looks like the PicoPSU is a bit light on this rail, and it wouldn't show up as much on the watt meter.

If you want a drive that is durable, get an SSD. They are completely solid state, and don't care if you slam them around.

As far as I know, any RAID array in XP will require a floppy disk (yes it must be a 3.5" floppy), with the correct files on it. You then press F6 during the initial stages of the setup and it detects the controller for you. The same ports when configured as single drives don't require this step.

drees is correct that all the benefits of RAID cannot be achieved with the onboard controller, but that doesn't make it a bad idea. You won't see the 4x read, 2x write benefits; it will be more like 1.8x write/read with ~3-5% CPU load, but that isn't really a big deal. It will still be faster and mo...

My system draws over 650W before PS inefficiency, and it's only going to get worse. I can see it going over 1kW within a year. Just keep in mind that "640k of memory should be enough for anyone." ;)

This is in my ASUS R2Hv-A1. Using "Notebook Hardware Control", great program.

Originally it ran @ 0.940V @ 1Ghz...a significant improvement!

Doubling power and noise almost doesn't matter with 2.5" drives in a desktop; they are so quiet to begin with. By doing RAID10 you will get 60-90% more transfer rate, but will get an ~5% hit in access times. 5400RPM drives already have a pretty lame access time as it is, so this will not be fast. Th...

I've noticed the design of the laptop and usage has a lot to do with it.

Just to muddy the waters a bit more here ;) Vista may be a red-herring. I've found that my laptops have gotten distinctly noisier over time due to dust/fur.

Cleaning off the thermal compound is a good start. Be sure to do what you can with the socket as well. Did you try re-seating the CPU first? Or a straight swap? The Opty might work after being taken out and put back in.

Do you think this would work in the P190? Yes, it would work fine in a P190. My 2 concerns are: 1. If the 140mm or 200mm fans aren't quiet enough, you are kinda screwed. I assume the 200mm fan is the same as I have here on the Nine Hundred, and it is borderline quiet. I'd love to get the spcr take ...

The most difficult thing to cool will be the video cards. There is the brute force approach, where you blow a lot of air into the case hoping that air will be cool and that it will escape somehow. And there is the finesse approach. By using cardboard/plastic/whatever to make all the air to the fan c...

Besides the issue with holes in the side panels letting out noise, my other complaint is with non-standard fans. They usually aren't quiet enough and are not replaceable.
