I used a RPI 4 with 8gb and both Astroberry and StellarMate for awhile. I now use a Mac Mini 2018 model. It has 4 TB ports and 2 USB and HDMI if you wish but I use RealVNC. It has great WiFi and I use a 4TB M2 pcie drive for images. I have run Ubuntu under Parallels on it too but running native on the Mini is easier. It is much faster than the RPI but cost $499 new when I got it in July.
