Question: After installing Win7 via USB and BT keyboard, will built in LAN operate w/ default drivers or are specific drivers required?
Document: It boots in about 8 seconds including the PLEX client. I transferred my Windows ISO to a USB drive and had it installed and running in under an hour. I run Win7 PRO so I can remote desktop in from my workstation to install software, etc (you could use VNC if you only have Win7 Home edition). This unit remains headless (no keyboard or mouse) on my TV.It's smaller than I expected - even smaller than I needed.
I loaded this machine with 16 gigs of RAM and Windows 8 - and it worked pretty well for a couple of months (I only use it on weekends, and it's connected to the flat panel TV in my den) then for some unexplained reason it lost its sound drivers and its LAN driver - I plugged in a USB ethernet adapter and got back online with it after which I tried to repair, and then reload Windows 8 and couldn't make it happen - kept getting error messages.
This unit is the perfect size for mounting to an LDC display to make a custom All-In-One system. I added a Logitech wireless mouse/keyboard to make my system only require two power plugs to operate. I also ordered a 1.5 ft HDMI cable to keep things tidy behind the monitor. Runs Windows 7 Ultimate very well.
There is a nuc with thunderbolt port that is capable up to 2560x1440 resolution but it doesn't have a NIC (Samsung USB to LAN adapter can help with this issue).Components:As this is a barebone kit, you'll have to add at least a memory and some type of storage to make it work.
Amazingly small! Wish it had USB 3.0 though : (Very fast!Extremely well built!Don't forget to get a local clover cable as it isn't included!
SSD and DVD are on dedicated ports. The other two (input devices) are on a USB splitter.Extremely glad to have both the media Center remote control and the wireless touch keyboard.
Here's the good and the bad:Pros:Small sizeLimited power consumptionSimple setup1080p HDMI outputCons:High price for not including memory, SSD, or even a power cableNo USB 3.0 portsIntel HD Graphics 4000 is not compatible with Directv2PCLimited storage options/spaceThis little machine is very easy to set up when it comes to adding the RAM and mSATA drive; it only takes a couple minutes and it's up and running. After making a bootable Win7 USB, Windows was installed within 30 minutes.
If there's no problems, I'll segregate the HDHomerun traffic on the USB adapter, and connect to a NAS on the Intel NIC via iSCSI for WMC storage.I'm leaving this at two stars. Intel should do better. Their NIC is pretty clearly a problem. *** UPDATE #2 ***I've moved the HDMI connection over, so that it's no longer connected to the port right next to the NIC. The network now seems stable.
This Intel NUC computer is perfect solution for an XBMC home theater PC.Setup with Windows 7 was fast and straight forward using a 32GB USB flash boot drive, although it did require manual installation of drivers for the Ethernet, graphics controller, and some misc. Intel support drivers. The performance is a great step up from slower ARM and Athlon based solutions. I have an Acer RL100 XBMC box and the NUC is much faster and it makes a big difference.
The 4-thread Ivy Bridge Core i5 processor at 1.8 GHz this delivers roughly 4 to 5 times the performance of a comparable Atom settop box or netbook or about the same as any current Sandy Bridge or Ivy Bridge based laptop or Core i5 desktop. 3 USB ports allowed me to hook up wireless keyboard and mouse in the back, and the front port I use for thumb drives. Awesome little device!
Answer: The DC3217IYE does not come with built-in Bluetooth so your BT keyboard won't work unless you install an add-on card.  I installed one of the Intel dual-band wireless cards with integrated Bluetooth in mine but Windows 7 did not load the Bluetooth driver by default.  You're best bet would be to download and install the updated drivers for the NUC and for any of the add-on cards direct from the respective manufacturer.  I used all Intel PCIe mini cards so the drivers were easy to locate and download from Intel's website.  Windows 7 installed a driver for the built-in LAN card but I recommend using the updated drivers from Intel.   Also note that you'll need to update the BIOS if you want to install more than 4GBs of RAM.
