Gigabyte Brix GB-BXBT-2807-1/4 Ultra Compact PC Kit - 1TB HDD + 4GB RAM

I bought two of these devices with 4GB RAM and 120 SSD to use as DNS / DHCP / OpenVPN servers on small company networks. At the point I bought these boxes they were advertised as containing Crucial SSD, however they both contained Plextor SSD which was disappointing.I installed Ubuntu 16.04 with the Intel graphics drivers and have DNS / DHCP / OpenVPN running. Everything installs without a problem, however I get frequent occurrences of the machines hanging i.e. the display freezes and there is no response from the box on the network or otherwise. I have checked the forums and tried all combinations of BIOS settings, both with and without the Intel graphics drivers without any change in the behaviour. It's the kind of problem where you think you might have solved it, but then it occurs again, so you're back to square one. In one of the devices the Plextor SSD failed altogether, so I replaced the disk with working 500GB ATA hard drive (not SSD), still the device freezes after an indeterminate time.I have found that leaving the machines logged in, with output being sent to the console that they tend to freeze, but when I leave them logged out (but still doing their thing) they have been running continuously for several months OK. They sort of work for the purpose I bought them, but as a desktop PC you can expect them to freeze up frequently while you are using them.

Very nice little box. With an SSD it really is effectively silent, although if you literally press your ear to it you can hear there must be a fan in there somewhere.I added 8 GB of RAM (be sure to get the low voltage stuff; I used (https://www.amazon.co.uk/gp/product/B006YG8X9Y) and a 120 GB SSD (https://www.amazon.co.uk/gp/product/B07G3KRZBY). I also got a dummy HDMI plug just in case but I didn't need it: the box runs quite happily without it or a keyboard.Installation was a breeze but I did find it helpful to take a few photos to make sure I got everything back in the right way around. No need to remove the WiFi module.OpenBSD installation went without a hitch and recognises everything significant apart from the WiFi, so far as I can see: DMESG======OpenBSD 6.5 (GENERIC.MP) #0: Wed

This is my first foray into the realm of small form PC's. I'm no stranger to PC hardware having been building systems for myself and friends and family for the last 15 years.Even if I had never seen a PC before, with the correct components this unit is incredibly simple to build.The additional components I added were:Ram -  Crucial CT102464BF160B 8 GB DDR3 PC3-12800 Unbuffered NON-ECC 1.35 V 1024 Meg x 64 SSD -  OCZ ARC100-25SAT3-240G 240GB ARC 100 Series SATA 3.0 6GB/s 2.5 Inch SSD  (which I had lying about as a spare so saved some cash there!)Input device -  Logitech Wireless Touch Keyboard K400 Plus QWERTY UK Layout - Black and I also purchased a  SanDisk SDCZ33-008G-B35 8GB Cruzer Fit USB 2.0 Flash Drive .Why the thumb drive? Download the Windows 10 ISO (https://www.microsoft.com/en-gb/software-download/windows10) burn it to the thumb drive (I used Rufus, available at https://rufus.akeo.ie/) and off you go!I built the system in about 30 minutes, which included making a cup of tea!Connected to my TV using HDMI and it's working perfectly. I use it for almost everything including browsing and running a PLEX media server and I couldn't be happier.I only turn the "main" PC on now for gaming!
