Question: I can understand the no RAM and HDD...but No wifi, bluetooth?...Fail!
Document: The price quoted is for plastic case, CPU, main-board and power supply only. You will still need RAM, storage, Wifi/Bluetooth and operating system which exceeds that of a Mac Mini by 100 to 150 which has all above plus inbuilt power-supply, thunderbolt and Firewire ports, SD card reader and aluminum case. If you prefer, you can run Windows too on Mac Mini.
It will be a bit noisy, but it can save you from a fried SSD! I have learned this the hard way (twice). If you have wifi, 2 sticks of ram and a ssd inside, it gets pretty hot. Also, mounting it to a monitor can add extra heat.UPDATE- I noticed that the latest units put a thick thermal heat pad above the SSD now, so that might help tremendously.
(See comments for info about vPro and AMT)(See end of review for Hyper-V info)My home ESXi box was already pretty green, drawing 45-110W depending on load despite having a quad core Xeon and 16GB RAM. Since all my storage was in two 4x2.5" Synology units pulling about 12W each, I knew the server was the next area for cutting power consumption.
Once I verified the motherboard chipset was not changing, and the i7 being cancelled, it was time to snag a couple i5 NUCs and set up a mini-cluster. I purchased 16GB of low voltage memory and a tiny 4GB thumbstick for each NUC as well.Going from one tower server to two NUCs gains me redundancy and twice the RAM, but similar performance (1x2.8 quad to 2x2.8 dual) and of course DRASTICALLY reduced power usage and physical size.
Having validated all the connections and testing the same network cord on my laptop, I looked closely at the network and saw that the connection was constantly dropping.
These are great little PCs. I used them to build some tradeshow demo units and they run nice and quickly and take up very little space.
So I would say this is somewhat misleading on the marketing side. Not enough for me to get steamed about, however, as my NUCs run at 800MHz 95% of the time anyway, which is great for my electric bill.
Hence keeping it at 5 stars. **** 07/02: Received the replacement and I am happy to report, the new unit does not have any of the network drop issues. This is a hardware issue which intel has acknowledged as well.
very capable box and very small. don't have an hdmi monitor where using so no sound. no optical or headphone capability. very powerful for most applications I am running and fast with onboard graphics. will upgrade to hdmi monitor or tv eventually and get better use.
I'm running Proxmox on this as a host for the various little utility servers I want to run in the house. It is currently handling my son's Minecraft server, our FreePBX phone server, and another Linux utility server with no issues.
Answer: The wireless card is only 30 bucks. And not everyone wants wireless.
