I'm a fan of AIO computers. I love the on-desk appearance of a quality monitor with only a keyboard & mouse taking up further real estate, but modulatory & upgradability in AIO PC's is understandably lacking and/or a PITA. That's where the NUC6i7KYK comes in.You're no longer limited to an AIO's integrated display until replacement of the entire PC. Purchase exactly which monitor you want, whenever you want. Upgrade and replace as you wish. Just make sure your monitor has VESA mounting holes separate from it's integrated stand to mount the NUC.Purchase RAM separately at your desired speed & capacity for the best market price available instead of shelling out the ridiculous premiums OEMs charge for higher RAM capacities.The ability to easily install two M.2 SSD's of your choice (NVMe and/or SATA).No disassembling a less user friendly AIO back panel and manipulating an unwieldy, display-sized assembly to perform hardware upgrades & maintenance. The NUC makes life easy. Simply unplug the NUC and slide it off the VESA mount (no tools required). Remove the four captive screws from the bottom plate and you've got access to storage and RAM.Do note the CPU is embedded, so you're committed in that department. I won't say you're stuck as the i7-6770HQ is a very powerful processor for this micro PC. In comparison, I had an i5-4690T in my last AIO and the i7-6770HQ is superior in most every way, especially graphics. The Intel Iris Pro 580 delivers ~3x the graphical performance of the Haswell desktop Intel HD 4600 Graphics and 2x that of the Kaby Lake mobile HD 620 Graphics according to UserBenchmarks.So what's the catch? Noise, but that should be expected with such a high powered micro PC. Cooling fan speed is adjustable, but will remain audible.Here's the part you need to remember so you don't make the same user error I did... If you use Bitlocker on your system drive, do NOT enable fast boot in the BIOS. Fast boot on the Intel Visual BIOS is not the same as fast boot on any of my other systems. On the NUC, fast boot disables USB until the OS is loaded, so you will not be able to enter your Bitlocker password to load Win 10 if fast boot is enabled.If you make this mistake, you will have to power off and unplug the NUC, open the bottom panel and remove the BIOS security jumper. This will allow you to get back into BIOS to disable fastboot, thereby regaining your sanity. Confirm Windows boots properly and shut down. Now reinstall the BIOS security jumper and get on with your life.Absolutely recommended!
