Pros: - low power consumption - fanless

Cons: - It took a long time for this board to finally be released. I've been waiting about a year. But it's finally here so now the demand will be high so it will just be out of stock.

Overall Review: I upgraded a headless Zoneminder system that was running on a J5005 to get a bit more umph. Load average seemed to go down by about 1/3 so that is good. (The J5005 NUC is now a MythTV frontend.) I also upgraded a MythTV frontend that had been running a J1009. The J1009 worked fine but was limited to 1080p. The J5040 boots in less time and also does 4K. Like the J5005, the J5040 loaded Ubuntu 20.04 with no issues. Everything just works. Also like the J5005 the J5040 has no problem handling 2 8GB DIMMs and providing 16GB (minus a bit for the video mem) for the OS despite Intel and ASRock both saying 8GB max total memory. (I suspect it may actually be 8GB is the max capacity of a stick but that's not what they say.) If you liked the J5005 you will like the J5040 as it is a the same but a little faster at the same price point. I wouldn't buy one to replace a J5005 unless you were planning on buying another J5005 anyway in which case you just buy this.

Pros: Makes a nice fast desktop for a relatively low thermal footprint and a great price point.

Cons: Processor lacks virtualization which means that a major feature of Windows 7 is not supported. I have a few apps that appear to need to be able to be installed in XP virtual mode in order to work on Win7(64 bit) and I can't do that. (It sure would be nice to be able to sync my palm!) Come on Intel. This is a relatively new processor and apparently one of the few in the Core 2 Duo line that doesn't support VT. Must have been the marketing people that came up with this one... D*mn I hate Intel marketing people.

Overall Review: May end up doing a "double purchase" and buying a processor with VT unless I decide to use my wife's laptop to sync or I decide to do it in linux once I get around to dual booting my desktop machine.

Pros: Small, quiet, low heat and power. Low power is great for a system that is on 24/7.

Cons: Limited to 8GB of RAM and while that is luckily just enough for my needs it would be nice to have the option of having more for some headroom. Note that this is a limitation of the J5005 SoC and not of the board design or UEFI; Intel chose to place this limit the processor itself presumably to limit its market and not have it eat into more expensive and more profitable chips. (Let's face it, this processor has enough horsepower for a lot of applications but 8GB puts a cap on things.)

Overall Review: I'm using this as a headless ZoneMinder box to monitor 5 HD/UHD cameras. Motion dectection is done on VGA resolution streams and when triggered both VGA and higher resolution (HD or UHD stream depending upon the camera) are recorded to a nfs mounted drive. Installed and ran Ubuntu 18.04 without issue.

Pros: - Compact - I didn't get cut up working on it like often happens with inexpensive cases.

Cons: - I can see how this would be very cramped and difficult to deal with if using a conventional power supply along with multiple hard drives. - The four thumbscrews used for the top of the case are rather tight. Not a major problem but it just seems like something wasn't quite machined right. - The Cool Master logo on the front is the power button and power light. It's a fairly bright blue. I may see about either adding a series resistor or perhaps scuffing the LED end of the light pipe to dim it some. - The hard drive activity LED which is on the side appears to be a conventional circular jumbo red LED from casual observation. It is kind of big and not the best look IMHO. It would have looked better if smaller, not as bright, and perhaps blue instead of red.

Overall Review: It worked well for me. I would buy this again. This is to re-house a MythTV backend server / NAS box into a smaller form factor. Intel J1900 based mini-ITX board, SSD boot drive mounted on the side, and two 4TB drives mounted up top. I used a Mini-Box 80W picoPSU with an external 12V brick instead of a conventional power supply and simply covered the power supply hole in the case with some sheet plastic. I can't imagine trying to deal with a conventional power supply inside this case with all of the hard drives and the cables. It would have been a challenge. I understand the reason for the length of USB cable as the makers of the case don't know where it needs to plug into on the MB. Unfortunately in my situation the USB3 header is very close to where the cable emanates from the case and it made cable management kind of interesting. In the end I wound up coiling the USB cable to effectively make it shorter. Not the nicest looking solution but it is functional.

Pros: I picked this up for my daughter who is a sophomore in high school taking honors this and that as well as an AP course. She wanted something she could use to read "fan fiction" during her down-time. On the utility side, I wanted it to be able to run MS Office so she could use it for school work. This has fit the bill perfectly. It upgraded to Windows 10 (free upgrade) and I was able to network map the DVD rom drive on my PC so I could install MS Office. It's not a powerhouse but it boots quickly (due to the SSD), had plenty of horsepower for MS Office, streaming netfix, etc. and it has excellent battery life. It's certainly not a gaming PC but that isn't what we expected or even wanted.

Cons: The display is fine for her young eyes. I'm a software developer that is used to huge 30" monitors and can get by with a 17" for surfing and email. Yes I can read things if have my glasses on but if you are in the 45+ club like me and are starting to have the typical eye issues associated with this age, then you probably want more real estate.

Overall Review: It's not super rugged but my daughter, who can be rough on things at times, hasn't caused any damage in the few months she's had it. This is a great system for someone who wants a small system to surf, check email, and type up term papers. The eMMC doesn't have a ton of space but I was able to install MS Office 2013 and still have a few gigs left over. I've installed a microSD card for data storage but honestly I don't expect my daughter to really load this thing down.

Pros: Using as boot drives on mythtv HTPCs. Boot time is incredible -- particularly for the price I paid. No moving parts so quite. No moving parts so fast. No moving parts so reliable.

Cons: They don't get hot enough to pop popcorn. As with all SSDs you need to take care so they don't die a premature death and if you are easily distracted it is easy to forget to do one of the suggestions that will minimize writes (and maximize drive lifetime.)

Overall Review: I see they now cost 50% more than I paid for them. I'm glad I bought them when I did as I probably wouldn't pay the current price as I was on a budget.

It used to be, years ago, when I ordered from Newegg I would get the items the next day -- maybe two days at most. That was using the cheap shipping. These days Newegg uses a lot of third party sellers. The Antec power supply I ordered shipped from Ontario. Not Ontario California or even Ontario Oregon, but Ontario Canada. Now I understand why the estimated arrival time was so long. It nevertheless arrived right when they said it would. That said, if there were a closer shipper I would probably choose them so I would receive the item quicker but this company did exactly what they said so I would definitely order from them again and can truly find no fault with them so they get 5 stars from me.
