Silent Power seeks funds for copper foam cooled PC

Campaign raises some red flags, though.

"minus applicable transaction fees" is suitably vague...

They basically mean you'll lose the PayPal fee - otherwise they'd be on the hook for a big chunk of change if they fall just short of their goal.

I thought the way these things worked was you made a pledge, then if the target was hit it was automatically charged to your paypal/credit card; if the target wasn't met then you wouldn't pay anything. In that case, why would there be transaction fees? Seems a bit cheeky if anyone is skimming a margin on a failed and refunded pledge, and it would definitely discourage me from crowd-funding anything if that's the way it worked.

That's how it works on Kickstarter and the other 'official' crowd funding sites, if you're pledging onto a project's own website then it's very much a free for all, be careful.

The Silent Power has other tricks up its sleeve, too: a sensor at the front of the chassis is said to detect the direction of movement of large objects within two metres. The team suggests it could be used to wake the system from sleep when you approach, or lock it against intrusion when you leave your desk.
If it can only detect large objects, how is it going to "protect against intrusion" when you're not at your desk?

By locking the desktop when you walk away. How else would it work? You can get software that does the same thing when your phone leaves Bluetooth range.

So if locks the system as you walk away does it unlock when you return? Because that could be anyone while you're away

No. Why would it do that? You approach your desk in the morning, the sensor sees you and wakes the system from sleep to a password lock screen. You leave your desk to get lunch, the sensor sees you and returns the system to sleep, or the password lock screen. Have you ever worked in an office? Every time you leave your desk, you hit Super+L to lock the system. This automates that process, just like the Bluetooth proximity example above.

Understand now?

EDIT: Although there *are* variants of the Bluetooth trick that *can* unlock the system as well as lock it, by exploiting the pairing between the phone and the desktop. The sensor can't duplicate that trick, obviously - just the locking part.

I like the idea in theory, but I can't see it being practical.

For a start, isn't copper foam quite soft and malleable? I could see the thing gradually becoming covered in indentations from the slightest touches and knocks. Not that that would matter too much, because it would surely become an ugly grey colour over time as it fills up with dust anyway - how on earth would you keep it properly clean? I doubt even vacuuming it would be enough to keep it looking nice.

The thing looks more like a theoretical wish-list than a proper business project...

More to the point, block scripts on the website and their fancy heading font disgracefully fails back to Comic Sans. Kill it with fire.

While I'm aware that hating Comic Sans is the cool thing to do on the internet I'd be far more concerned about the fact that every other PC Cooling Revolution in the last 10 years or so has turned out to either be fake, only work in lab conditions or be prohibitively expensive rather than the choice of font.
