It doesn't exist yet I'm afraid. I've been looking for a H55 mini-itx board with two nic's for much the same purpose. Think I'm going with the supermicro X7SPA-H, which is of course atom based so rather slower. For HD playback, atom + ion or atom + broadcom decoder card (mini pci-e) is an alternativ...

There is always a tendency to look at a system selfishly. I believe I would benefit from a thermoelectric system, so assume others could do as well. Please allow me to address some of your points. Radiators tend to increase the size of cases. There's not very much to be done about this besides using...

I've done this, probably got a link around here somewhere. Definitely a success, though my computer is really not fun to carry any distance

Water is more expensive. It is however better in every other way than air. For performance, and for silence. Performance I'm going to take as obvious, but silence is worth clarifying. The normal approach to watercooling is to use a pump to move hot water from components to a radiator. This allows yo...

Do you see the potential for fast, small systems? Specifically when you want to minimise size and/or noise while maintaining high performance, but don't care that much about electrical cost. Below ambient cooling with peltier's is unpopular, as their only advantage over phase change is noise. Not ma...

There's no absolute reason against this. When water heats up, it will decrease in density, and this can be used to move it around. It would be rather difficult to estimate how well it would work, but it's probably an interesting thing to attempt. Radiator would need to be horizontal, and physically ...

This isn't going to be a useful reply as it's nothing to do with windows, but what the hell... Under linux (certainly Debian, I assume the rest do it as well), the command sdparm will spin down hard drives. Hdparm will do it for pata drives, sdparm for sata and external usb ones.

Sucks when people put down a technology that they clearly don't understand. Below ambient cooling + silent is a very difficult combination. Not impossible, but certainly unusual. Peltiers are not particularly inefficient, but they do require electricity. Under best case conditions you're looking at ...

Bit of necromancy, but Google threw this up as a top hit so why not. I'm stunned that no one has mentioned that hard drives spin down on command. An ssd with a 3.5", 7200rpm is fantastic for silence since you just turn the hard drive off when you're not using it. As a storage drive, that's most of t...

Hopefully one brick will be sufficient, but if not I'd want to use two bricks with one pico. One mains cord running to both bricks, then splicing all six grounds together and all six 12V also together. Then run cpu/gpu from this 12V rail and use a pico to convert the 12V into the 3.3, 5V etc which t...

The attraction of the pico is it's size and the lack of fans. A mini-itx case which doesn't have to fit a psu can be significantly smaller than one which does need to. Plus I want to learn some more about computer electronics and this seems a fair starting point. Happy to hear the wires are joined a...

Thank you, that's very useful. Continuing in the same sort of vein, were I to buy two DA-2 supplies, plug them both in, and wire all six ground lines to each other, and likewise all six 12V lines, will it all work out well or will the adapters object? I can't help feeling using two of them (for 36A ...

Galvanic corrosion won't be noticable after a week, but after half a year it will be, if you don't take precautions. No physical contact between aluminum and copper is needed, the coolant will be the conductor. There's very little evidence for this, despite it being "common knowledge". The odd grou...

The 750S is a lot more expensive for those 10W, I'm sure you can achieve the same tdp by undervolting a normal 750. You're borderline regarding psu. The biggest issue is that the 150W pico can't output anything close to 150W if it gets hot. For that matter it can only do 8A at 12V anyway iirc so I d...

Joining the rails on a Dell DA-2 together, this alright?
The Dell DA-2 is mentioned in various places on these boards, the main point is that it provides three wires at 12V, three wires at ground, and offers six amps on each of these three rails. The approach used in a thread on here was to connect two of these lines to a 150W pico-psu and the other to th...

If you do go down the mass loading route, Flashing tape / roofers tape / bitumen with foil cover on one side is well worth a look. It's about 1mm thick, self adhesive, dense, very cheap. The thickness lends itself to application almost anywhere, and the price to using many layers if you wish to. I b...
