    A difference of 41C to 55C is substantial.
    Because the aluminium case is in contact with the CPU and is a much better heatsink than the small attached one.

    Ah, that makes sense then. The brief sales description on Amazon doesn't mention that. I took a look at more detailed description and can see how it and the Flirc case make that direct contact.

    .
    Because the case is the heatsink, the Flirc case "touches" the CPU ;-)

    My regular LMS with large local library is on a 3 and it works well.
    +1 my LMS setup ran on a Pi2 for several years (both server and player) with no problem at all. That said, given the price, unless a cheap second hand Raspi3 is available just go for the Pi 4

    Hi,
    I'm a rPI newbie as well, and could do with a steer on what HW I need. My application is slightly different to the OP as I'll need a DAC+HAT.

    Briefly the requirement is to create a portable radio player plus server, it'll need:

    - to be an LMS server/player, so Pi Core I think
    - some form of display/control, possibly Slimmer
    - low power/battery, TBA
    - ability to take an SD card with music
    - WIFI, possibly wired ethernet also
    - will need to drive some speakers, so DAC+AMP (~30W) req'd, possibly line out also
    - decent quality required but not audiophile

    My thoughts are Rpi4 (4gb?), Pi-core, Slimmer, +DAC/AMP (which one?), but would appreciate advice on the rPI and DAC/AMP versions.

    Budget for rPI+DAC/AMP somewhere between ú50-100 GBP

    the rpi4B and piCorePlayer OS for sure.... 4GB is plenty. Depending on your music library size, you can also have music on the SD card in addition to the OS. But I'd recommend you have the music on either a USB external drive or a USB thumb drive. I use lots of these 4TB portable drives for this purpose, and they don't require any additional power supply (powered from rPi USB socket).

    Thanks for confirmation on the rpi4B Gary.

    Anyone have a recommendation on the DAC/HAT/AMP for decent sound @ around 30W at reasonable price?

    I have a 3B+ with a hifiberry DAC + Pro that I use and really like. But it feeds RCA inputs of a small preamp/amp. I haven't personally used a DAC/AMP HAT, although I see others reporting satisfaction with such setups.

    Have you done some calculations for the battery size you will need?
