Maybe you need to think what you want from your set up.

Is it for "in the field" or just in the Obsys ?

Do do want minimal number of wires ?

Do you want very high frame rates ?

Are you going to rely on very fast plate solving?

Can you back up your system - people underestimate the time it takes to rebuild and tend to forget the little changes they made. SD card are slow but its so simple to backup and the cost is low.

As Indi provides Client Server set ups how will you benefit from from everything on one PC

Is there enough support for your future device (both Indi and OEM) and be honest do you know enough (or want to learn) about the curing niggles.

If its in your Obsys and you are not bothered about wires but just want a single PC set up which you can remotely view then think about buying a second hand ex corporate high end PC which can run Indi - So I7/i5,16GB memory , 1gb SSD and separate large HDD, high end graphics card, USB3 ports galore and both wireless/wired Ethernet. Just make sure its Linux hardware compatible - get he seller to run a Linux livecd/usb or check if manufacturers site. £300 should get you a high spec "game" or desktop/server which will do everything very fast.. Dont forget the graphics on the viewer PC else what's the point you will see down graded images via Teamviewer/VNCviewer etc

etc etc

You have obviously already started to think about it by asking others who have done it so more time spent thinking may help with minimising long time pain/frustration.

Even in this modern world a piece or paper and a pen writing down your requirements counts for a lot IMHO

I explored the optimum mobile environment and set the INDI environment for the following Mini Computer and SBC.
· RPi 3
· Orange Pi + 2
· NanoPi-M4
· Beelink AP 34
· Goal 1
Ultimately, PCs such as Arm type chipset and Atom chip do not have enough system device drivers for UBUNTU itself, and their functions do not seem to be sufficient. It takes time to solve it.

Beelink AP 34 was able to set the INDI environment most easily among the above.
Because this PC uses Intel's chipset, it took less time to install and setup the system device driver.
Probably Intel's NUC is the easiest to set up.

In the Arm system, I think it is easy for RPi 3 to build the most stable environment at the moment. (Arm family second best is NanoPi - M4 (in my case))

For what it's worth, I run my whole imaging rig from an Intel Compute Stick (CS125), which retails for about $130. Quad-core atom x5 Z8300, 1.44 GHz, 2 GB RAM, 32 GB eMMC, dual-band wifi, 1xUSB2, 1xUSB3. The computer weighs just 62 grams and is easily attached to the scope with velcro. It is powered from micro USB and draws less than 5 Watts (usually about 0.5 amps at 5 Volts).

I run straight-up Ubuntu 18.04 on the stick, and installed InDI, KStars, TheSkyX, and PHD2 without a hitch. Performance is fluid and snappy. I run the whole client session from the stick, saving the images to a 64 GB micro-SD card. I *don't* run the devices off the InDI driver on the stick with the KStars client running on a more capable machine inside. Rather, I use TeamViewer or VNC from indoors to set up the run, then let it operate unattended all night and collect my pictures in the morning.

I've been playing with the little compute sticks for years, first with Windows (SGP and PHD2 and TSX) and then more recently with Ubuntu. Windows was a dog on the stick. Win 10 Home 32 bit was pre-installed, but can't download a big image (my imaging camera is 7376x4928 pixels). I installed 64-bit Windows which can handle big images, but performance really lags.

By contrast, Ubuntu performs great on the stick. I don't notice any performance lag except maybe with plate solves. I don't run Lubuntu or Mate, just out-of-the-box Ubuntu 18.04 with Gnome 3 Shell. Everything installed right away and runs great.

And the dual band (5ghz especially) wireless worked without downloading drivers from Intel ??????

Did you switch off the BT ?

When I looked at the Stick I discounted it as Wifi had many issues even on Windows - Cloudynights had some reports of the issues. Maybe I should have persevered :-(

@stash: I have not had any problems with wifi on the stick(s). I have never used BT with them, but don't recall having to switch it off either, and no I never downloaded wifi or network drivers. Basically worked out of the box, though I was unable to get 32-bit Win 10 to work with my camera so I installed ubuntu.

I use it routinely in my back yard (home wifi is 5 GHz) and at my mountain cabin where I use 2.4 GHz.

They solved all the issues with putting Ubuntu on these Atom sticks with the latest Ubuntu 18.04.1... it was the previous versions that had all the WiFi driver issues... :)

Does it have to be an SBC? I bought a second hand office desktop PC on ebay that sits by my pier. Its a bit bulky but works really well. Its just an intel i5 with 8gb ram. Pretty basic but for the last 2years its worked very well. I can power it on remotely using wakeonlan.

No of course it’s not just SBC any computer that will run Linux can be used.. :)

+1 for the Rock64. I use it for indiserver and phd, and have just installed astrometry.net on it. I have it with a 32 Gb card, but would beed to upgrade to 64. I believe that I was one of the furst people to use thus sbc. There were a lot of issues in the beginning, but now it's well supported and very stable.
I use it with ubuntu 16.04
