Great that in some months there will be a high-end laptop that you don't have to throw in the garbage bin once a ram chip fries. High expectations.
Well, there already is. I really like my Framework 13.

#52I don't know if magnesium is a common choice for computer enclosures, but one of the few examples of magnesium that I immediately recall (besides Surface) is a NeXT computer that went up in flames: https://simson.net/ref/1993/cubefire.html
The ms surface books were magnesium I think.

#54Surprised to learn that magnesium is lighter than aluminum. Is it also more expensive? There must be some reason people still mostly use aluminum.

Quick search says its about $1 more per kilo

My definition of “high end” in 2023 is a battery that last 14+ hours of general use, doesn’t sound like a 747 when I open two Chrome tabs side by side and won’t fry my nuts when I put it on my lap.

#59Earlier quoted context omitted.
Sorry for the stupid question, what is the advantage of your new connection for gpu? why not oculink or pcie riser or thunderbolt?
PCIe is too physically large, Oculink is too thick and doesn't have enough pins for power, and Thunderbolt has protocol overhead and throughput limitations.
It seems to me that oculink port is still a good option for side module, although it's unrealistic. I hope ltt lab create custom gpu module from the desktop 4090: built-in power, water cooling and of course rgb :)

#60Good detail hear about the process if making the case - really interesting to read. Injection molding semi-liquid magnesium seems…quite difficult to say the least! Tangentially, I wish there was some online resources for learning how best design for manufacture for things like laptops and cases. Contract CNC fabrication is really inexpensive these days until you need 10 iterations to fix your dumb mistakes.
The fastest way to learn how to make machinable parts is to machine them yourself :). DFM is often a hard-earned skill. Unfortunately maker-spaces (the only kinds of places where you could get cheap access to good 3+ axis CNC mills) seem to have gone out of fashion. CNC mills in general cost about 5 digits just for the machine, and usually that again for the tooling. I think the closest one can get to learning some D…
You can get into cnc the diy route for between ~$2k and ~$8k depending on the amount of rigidity you want. There are conversation kits available for common import mills to make the process relatively easy but the control and wiring isn't for the faint of heart.
I built one out of a PM-833TV and it's taken years to get working well, and I probably should have just bought a used HAAS at this point, but if you build it You Will Learn one way or another.
Words of wisdom I wish I'd had: spend the money on decent over specced servos with ethercat. Don't skimp or you'll end up having to just redo stuff and it'll cost a lot of money. Do not buy stepper motors period.
