Before Thanksgiving 2016, I purchased an Intel NUC 6I5SYH ($319.99 on sale at Microcenter, late-November 2016) to serve as my new home desktop computer. This review/guide is based on my initial setup of the 6I5SYH.
The Intel NUC 6I5SYH is a small form factor (SFF) bare-bones personal computer from Intel’s “Next Unit of Computing” line.
The 6I5SYH includes an enclosure (approximately 4 1/2″ wide x 4 3/8″ deep x 2″ tall), motherboard with a soldered i5-6260U CPU (Skylake, or 6th-gen architecture–1.9GHz up to 2.8GHz Turbo, Dual Core, 4MB cache, 15W TDP), wall-mount power adapter with multi-country AC plugs, and VESA mount bracket.
The 6I5SYH’s motherboard supports the i5’s integrated Iris 540 graphics over a built-in HDMI 1.4b or Mini DisplayPort 1.2, and it includes 2x USB 3.o ports (back), 2x USB 3.0 ports (front and one supports charging), 2x USB 2.0 headers (on motherboard), IR sensor, Intel 10/100/1000Mbps ethernet, Intel Wireless-AC 8260 M.2 (802.11ac, Bluetooth 4.1, and Intel Wireless Display 6.0), headphone/microphone jack (front, or 7.1 surround sound via HDMI and Mini DisplayPort/back), and SDXC slot with UHS-I support (left side).
The 6I5SYH requires the user to supply a hard drive or SSD, and RAM. For permanent storage, it has internal support for an M.2 SSD card (22×42 or 22×80) and SATA3 2.5″ HDD/SSD (up to 9.5mm thick). For memory, it supports dual-channel DDR4 SODIMMs (1.2V, 2133MHz, 32GB maximum) across two internal slots.
For my 6I5SYH’s RAM, I installed one Crucial 8GB DDR4 2400 BL SODIMM ($44.99 on sale at Micro Center, late-November 2016), and for its SSD, I installed a Silicon Power S60 240GB SATA3 SSD ($67.99 on sale on Amazon, December 2015). Excluding the costs of a monitor, keyboard, and trackball, this system cost $432.97.
After first assembling the 6I5SYH with its RAM and SSD, I booted it and went into the BIOS (press F2 at the boot/Intel screen) to check its BIOS version. Based on everything that I had read about this and past Intel NUCs, it is always advisable to have the most up-to-date BIOS installed. Sure enough, it reported having BIOS 0045, and a newer BIOS had been released (0054) according to the Intel Download Center page for the 6I5SYH.
I downloaded the new BIOS binary file to a FAT-formatted USB flash drive on my Mac, inserted the USB flash drive into a front USB port on the NUC, pressed F7 to update BIOS, and followed the prompts. After confirming the BIOS had updated, I turned the 6I5SYH off by holding down the power button on its top plate.
Next, I used the Fedora Media Writer for Mac OS X to create a bootable USB flash drive of Fedora 25 Workstation using the same flash drive that I had used to flash the 6I5SYH’s BIOS.
After the media creation was completed, I inserted my Fedora 25 bootable USB flash drive into a front USB port of the 6I5SYH, powered it on, pressed F10 for the boot menu, and followed the prompts. If you need an installation guide for Fedora 25 check out the Fedora Documentation here, or if you need a screenshot walkthrough of installing Fedora 25, check out this guide.
After installing Fedora 25 with full disk encryption, I installed updates and began installing additional software. The guides here and here offer great advice (there are others for “what to do after installing fedora 24” that have useful info, too) on what to install and configure after a fresh installation of Fedora. Some that I recommend include Gnome Tweak Tool (available within Software app), Yum Extender (DNF) (available within Software app), VeraCrypt, and VLC. Remember to install RPM Fusion free and nonfree repositories–directions here, too.
So far, Fedora 25 has performed wonderfully on the 6I5SYH! Out of the box, the graphics, WiFi, Bluetooth, USB ports, and SD card reader have worked without error. I am using a Mini DisplayPort to VGA adapter to connect the 6I5SYH to a less expensive VGA-input LCD monitor. I am watching 1080p Rogue One trailers without a hiccup, and I listen to Beastie Boy MP3s while doing work in GIMP or LibreOffice. I have not yet fully tested virtualization or emulation (consoles or vintage computing)–these are my next steps.
The 6I5SYH is snappy about doing work, and it is quiet nearly always except when it first boots up (and the fans spin up high momentarily). For the features, size, and price, I highly recommend the 6I5SYH as a desktop replacement that runs Fedora 25 and common Linux programs quite well!
