The machine I’m using right now, which is just about a year old, is practically overflowing with USB-A ports. But it only has one USB-C
port. How long has USB-C been around?
Here is a concept that does away with USB-A completely, and ends up
bristling with USB-C ports instead.

I'm still old school...I want a motherboard that has half a dozen *simultaneously usable* PCIe slots.

I don't really see the point of putting a lot of USB ports in the back
of a computer in general. Aren't they a little hard to reach? And do you really need 10?

In my house just a couple of weeks - I used my first USB-C device
last month, via a cable to a USB-A plug. Another flimsy little
connector that I'm likely to break, like devices with MicroUSB
connectors, when I accidentally catch the cable with my arm and
yank them about.
The USB-PD standards are interesting. Upon first reading about them
I was keen to find/design a device to just break out the outputs
and have a mini variable power supply for general use, even battery
powered from one of those power bank devices. But as with most
things USB3/C it turns out the power supplies that are actually
available only implement the bare minimum range of voltage outputs
that the manufacturers think most people will need.

Mine here are all 5/9/15/20V. I "think" they're missing only 1 or 2 voltages, but that's enough for my laptops and cell phones. Not really
sure what'd ask for 9 or 15 volts ...
Bear in mind that it's ONE output, and you negotiate the voltage on the
wire as part of the connection handshaking (IIRC CC1/2 or maybe
something more active later on, been a bit since I read up on how PD
works)

9V plugpacks are pretty common for stuff I use, it's typical for
devices that reduce that to 5V internally. Similarly 5V devices
generally use 3.3V internally. My laptop's power supply is 16V, so
15V might work.
But really what excited me were the newer PPS power supplies (USB-C
3.0 PD PPS, to use their full title). These are supposed to supply
a requested voltage in 20mV steps between 3.3V and 21V+. The idea
is to allow optimised battery charging by supplying a charge
voltage/current specific to the state of charge that the battery is
in. I just liked the idea of completely universal plugpacks, but
when I went shopping for them (and granted they're quite new to the
market in Australia) the models on offer had a much more limited voltage/current range.

Yes it's all rather complicated, but in theory a device to allow
manual control of the output could be quite cheap because there
are chips designed for doing that in relatively dumb USB-C-powered
devices. However I found a project online from someone who'd tried
making a bench power supply adapter from a wide-range USB-PD PPS
power supply and they found the outputs were so far off what was
requested that they ended up setting it to a fixed output and used
another regulator for the final output. So not using the voltage
programming ability of the USB power supply after all. I realised
then that I was probably wasting my time - it's a standard for a
perfect power supply, which might only be used to make barely-good-enough-to-sell power supplies. I shouldn't really have
been surprised.

Not sure what a "9v plugpack" is -- maybe something leaning a little
more "professional grade", like what photographers tend to carry
about?

All of my "5v(tm) devices" are certainly running lower voltages inside
-- batteries are only 3.7 to 4.2 volts (or thereabouts) anyway, and I
know my phone has a lot of 1.8 volt things inside.
I was more saying that I couldn't really think of anything that'd take
the middle voltages, given what I'm familiar with.

Happen to have a link to the project? Or was it something you came
across ages ago?

As Rich suggests others call them wall warts, though I thought
plugpack was actually the more universal term for them. Power

I definitely did.
My Newsreader had the message stuck in the outbox and on a retry loop...and I didn't realize it was posting with each failed attempt. I left it running, and I just sorted it out.
I can't believe how much spam I accidentally created.
