I have ordered a RPI 4, 2G board and a RPI Zero W board, plus some accessories from Buyapi.ca, today. :-)

I am interested in a couple of projects where the Pi Zero W (a very small stripped down Pi with wifi) is used with a very small audio amplifier board, to build a very small, Internet radio receiver.
Another Pi Zero project is to use the PI Zero to build a very small, very low power FM transmitter.

The  RPI 4 is to replace the RPi 3B that died, on me. There are also nice projects that make use of the RPi 4, as well. :-)

I'll be looking forward to your reports on the rPi4!

From what I have read, in comments about the RPi 4, is that it runs quite hot.  If the RPi 4 is doing any moderate to heavy computing then you need to provide the CPU with active cooling.  Either a very large, heavy heatsink or better, a very good fan or fan/heatsink.  Any enclosure, would of course, need to be well ventilated.

My RPi 4 and RPI Zero W and accessories arrived in the mail today. :-)

Sweet! Did you get it with a big heatsink or fan as Fox suggested? I noticed the Raspberry Pi 3 ran hot, too. In the summer, it'd show the thermometer whenever I was doing much of anything on it. But when I put it near my personal desk fan, I noticed that disappeared. So, I had a cooler, and didn't know it!

Yes, I got the heatsink package that has a large rectangle heatsink to cover the 2 adjacent chips and there are 2 small fans that mount on it.

What case did you buy? Could you post the names/brands of everything you bought for your rPi4?

I didn't buy a case, yet, because it looked like the one's  they had, did not have any ventilation slots to let the heat escape the enclosure. I will search elsewhere for a better case.
Here is a snapshot of what I ordered.  Note, I bought the 2G RPi 4, because I thought the extra $30 for an additional 2G of memory was a bit excessive, for a 4G RPi 4.
They had a better, slightly higher price fan system with a small circuit board to better control the fan but I didn't want to  block access to the header pins, that this circuit board may have resulted in.

Is the mini-HDMI to HDMI for the Rpi Zero?

Yes, the adapter is to use with the RPi Zero.

Be sure to let us know what you do with the devices, particularly the Zero. I'm interested in what it's capable of. At one point, they were giving them away with a UK Linux magazine. How much did it cost you?

The RPi Zero W was $21.  I had to also pay shipping but I was ordering the other items, as well, so it basically didn't cost anything for shipping.

Decent price. Who would have imagined even 10 years ago that we could get a mini computer for under $50?

We never did find out what you used the RPi 4 for. I had forgotten that you bought the 2gb model. Did that turn out to be too limiting for your use? As you know, I am again considering buying a 4 to replace my 3B, but I still don't know whether it's worth an extra $30 to buy the 8 gb model. I would buy a 4 gb at minimum.

Also, what are you using the zero for?

I haven't used my RPi 4 yet, because I bought it to replace the Pi 3b that died. Since then I was able to get the Pi 3b working again, so there was no pressing need to start using the RPi 4.  Now however, the Pi 3b has died again, so I will now have to setup the RPi 4 as an internet radio.

My very first post in this message Forum, also mentions why I bought a Pi Zero with wifi ( to also turn it into an internet radio). :-)
