I recently acquired a modestly spec-ed GMK NUCBox with a J4125 Celeron core, 8GB RAM, 512GB worth of storage. I've opted to put N.I.N.A. on there along with all the usual associated packages (PHD2, CDC, ASTAP, etc.). This setup is used for acquisition only, not for any kind of post-acquisition processing. As my camera is an ASI6200MM, I'd be downloading 122MB files. Whilst I don't expect this to be CPU intensive, I would be running USB3 for quicker downloads.
Despite not expecting to be CPU intensive I'm still running within tight constraints. I understand that using something like VNC has a slightly higher overhead than RDP from a CPU resource perspective, but I'm curious if wireless HDMI dongles to an untethered 4K portable display (with bluetooth keyboard/mouse) would be even less intensive than RDP/VNC solutions?
Does anyone have both and have practical experience on this? If so, which is your preferences? Aside from the CPU resource perspective, is the wireless HDMI more responsive from a GUI perspective?
Edit: I should add that initially I was thinking of Miracast (HDMI over Wi-Fi) but I am open to independent HDMI transmitters/receivers too although they are bulkier.
I am assuming the NUC is to be for a scopeside computer? If so, just about any quad-core celeron with 8-gig will be just fine. My own NUC which I have been using at the scope for the last year has never failed me. I use tightVNC and have never had any issues whatsoever. (FYI, mine is much older and less capable than the J4125, mine is powered by a J3455, circa 2016)
There is lots of misinformation about NUC's being bandied about, I wouldn't pay attention to the naysayers.
Stuff you should know:
Nuc's run just fine headless, you don't need an hdmi dongle.
Nuc's run just fine on 12 volts.
You don't need an i9, i7, i5, or even an i3. If this is truly a scopeside computer, all you are doing is running image capture and guiding.
I use APT and NINA, the image files are all downloaded directly to the nuc where the image capture software is running. When the session is over, I can pull them over the network to my image processing computer, or simply offload them to a memory stick and handle it that way. Unless the NUC will be at some remote site, I don't see any reason to be concerned about network bandwidth.
Not sure why a 4k screen would be helpful for running image capture software and PHD2. But in any event, NUC's are designed with 4K in mind, as they are marketed heavily as entertainment PC's for video streaming.
Good luck with your project.
