Pros: I've now purchased 2 of these: one for myself (as a HTPC running XBMC and also just for lightweight computing) and one for my parents (as a full replacement for their primary desktop). These things are fantastic. Once you buy the RAM/mSATA storage, you can whip it together and install Win8 in under 20min. The Intel VBIOS is one of the cleaner modern UEFI interfaces I've seen (unnecessary animations can be disabled). You need to spend some time tweaking the temp/cooling settings in BIOS if you want to truly minimize ambient noise, otherwise the fan kicks on a bit excessively. Both the mini-DP and mini-HDMI ports support 1080p and digital audio, so you can easily hook up to any TV (dongles can be found for cheap on Amzn). Power brick is slimmer than most laptop power bricks I've seen. No built-in battery backup tho, so make sure you use a UPS or otherwise risk data loss.

Cons: The price is high for the modest specs, you're definitely paying for convenience of compact form factor. Also, the price hasn't gone down in the last 1year that I've tracked it (in fact it's gone UP by a few bucks). All the ports are USB 3.0. This is nice as a future-proof feature. However, there is a known and documented incompatibility with USB3.0 standard and USB wireless receivers operating at the 2.4ghz range. The Logitech wireless dongle that I use does not work when plugged directly into the USB3.0 port (at distances >1m, interferences from the USB3.0 port causes the wireless signal to be disrupted). Workaround is I have to plug the dongle into a USB ext cable. It works but is a bit messy, and I really wish the NUC had just *one* USB2.0 port so that I didn't have to deal with this workaround.

Overall Review: pairs nicely with Mushkin 120gb mSATA storage: http://www.newegg.com/Product/Product.aspx?Item=N82E16820226320&ignorebbr=1 and also G.SKill 1.35V 8gb ram chip: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231704 Haven't tried the built-in WiFi/Bluetooth antenna (separate card req'd). Also haven't tried the built-in IR receiver. So cannot comment on those features.

Pros: Quite impressed with the performance of this little guy, response is very snappy for a dual core. Capable of streaming 1080p 60 FPS to multiple monitors. It's an excellent desktop replacement (time to get rid of all those huge outdated desktops) and easily mounts to rear of monitor with included vesa mount.

Cons: Non thus far

Overall Review: My NUC setup Intel 525 mSATA drive, 8GB Crucial memory and Windows 8.1 pro 64 bit. Intel Bios are also quite impressive with lot's of features which are very versatile for different configurations. For security it has Secure boot and TPM (turned off by default). I have plans to replace all my huge desktops with NUC's. The Haswell NUC's now includes power cord (it's a complete kit). Wished Intel made a dual NIC model, this would make an excellent small form Untangle Server!

Pros: Love it. Originally was considering one of the Booksize Barebone PCs by Shuttle or Foxconn and purchased the Asus EB1033-B0100. The fan noise was an issue with the Asus - it's a typical laptop fan so if it's hidden you probably will not hear it, but I needed something silent in the bedroom as it's a 24/7 email server for me. I picked up this unit along with the Akasa's Newton H Fanless Solid Aluminum NUC Case (from frozencpu.com) and now it's completely silent and the temperature dropped 5C. Used the Tuniq TX-2 Cooling Thermal Compound sold here on newegg (eventhough it comes with some). Running Ubuntu 14.04 and previously 12.02 and everything worked/recognized out of the box - thankfully! Both Server and Desktop version tried too. Even a Dell DW1506 WiFi card I had lying around worked out of the box, and a bluebooth usb dongle (Broadcom ccbt2035bdgp23-2, vendor 0a5c idProduct 200a for anyone who has one too worked). The only thing I did not test is the Infrared sensor. For those keeping the original Intel case it is quite nice with metal on the sides, plastic on top and bottom for the wifi signal, with an inner metal housing around the sides. Quite small as you can imagine that truly fits in your hand's palm. Go to Intel's site about their NUC series to learn more - it can be quite confusing with all the models, but it really comes down to three latest units - i5, the i3 and the Celeron and three prior generation models. The new series also has models that allows for an SSD laptop 2.5" drive too which simply gives a case with greater height. The motherboard itself is the same and includes an sata port on the motherboard. I prefer the i3 simply because it's using the 4th generation chip which uses less power and hopefully less heat and powerful enough over the Celeron without breaking the bank. The NUC series seems to be building up a great eco-system too which I hope will continue. Def check out the Akasa's case..it's $99 but completely solid metal (~3lbs alone) and the second only to another brand that simply isn't sold in the US so go with this. I found most of these fanless brands cases are made overseas. Do not buy the $30 alternative by SilverStone PT14B-H1T1 as reviews online shows temperature actually goes up. Remember, the more metal the better. I couldn't be more pleased with my combo, even under heavy load the temperature only rises to about where it was with the fan at idle.

Cons: None so far, works with Ubuntu and from reading other reviews here and else where, Windows would be fine too should I ever need to switch.

Overall Review: The BIOS' gui is quite nice as well! Plenty of options and information.

Pros: Small and powerful.

Cons: Fan may be noisy or failure-prone.

Overall Review: Along with my new i5-4670K gaming build, I bought the NUC D34010WYK just because I had to have one. I also bought an Akasa Newton H anodized aluminum fanless case (not available on Newegg), 2x4GB Crucial SODIMMs, a Crucial 120GB mSATA drive and the Intel 802.11ac+Bluetooth wifi card. The result is a screaming fast, completely silent system with no moving parts. Windows 7 SP1 Ultimate x64 installed in about 5 minutes from a live USB flash drive. I ran OCCT Linpack on it for 2 hours, 100% CPU usage and 90% RAM usage, and the CPU temperature topped out at 54C, no errors (I used Tuniq TX-2 thermal compound when I installed it in the Akasa case.) This system will handle just about anything you can throw at it, except for the newest, most bloated video games. The most common complaint about these NUC systems seems to be that the fan is sometimes noisy and prone to failure, so I strongly suggest getting a fanless case from one of the manufacturers currently producing them. The Akasa case has holes for installing two external antenna mounts. You'll need two U.FL Mini PCI to RP-SMA cables and two external antennas to complete a proper installation. Otherwise, you'll have to peel the small copper antennas off the inside of the factory NUC case and install them in the fanless case, a sloppy solution which will result in poorer wifi reception.

Pros: Small size, quick, easy to access components and of course the Intel logo sound when you open the box.

Cons: You have to read the acceptible ram chart. Now while it will probably take any 1.35 volts ram. best not to take too much of a chance on it. I didn't read the part where it said to get 1.35 volt ram. (IT actually does not say you must get it...It should) I instead gotthe cheaper 1.5 volt stuff. Well the unit won't even turn on, No internal speaker so you can't hear any bios beep codes. There is however a flashing power button that itdicates the ram is the culprit. RMA'ed the 1.5 got the 1.35 and all is right with the universe once again.

Overall Review: The ram I picked up for this unit was CT2KIT51264BF160B. And it is working fine. All in all it was only a few dollars more, which I spent more RMA'ing the wrong stuff. Lesson Learned...Read the manual

Pros: Super Small. Barely Audible. Plenty of Power.

Cons: Wouldn't Mind If It Was Cheaper. Wireless Antenna Weak.

Overall Review: Seriously this NUC is great. I was torn between this unit and the i5 version. Glad I saved the extra $100. I use this only for XBMC and can use hardware decoding or software decoding with no issues. It plays every file format I throw at it without frames dropping. I might buy a couple more to replace my other units. My only real complaint is that the wireless antenna has terrible reception. I picked up the Intel Dual Band 802.11ac unit and I get almost no signal on 5ghz with my router in the room directly below this but full signal on the 2.4ghz band.

Pros: Nice, fits well in my kitchen, a nice low profile. Works well... fast ship... good price... I won! :)

Cons: none

Pros: Small,quiet....This unit once I installed the Samsung msata and Gskill so-dimm memory is incredibly fast! It's size has helped with space in the kitchen. The unit feels cool to the touch.

Cons: Can't think of any for a kitchen pc. It can do everything our large kitchen pc could do in 1/10th of the space.

Overall Review: Wish Intel would just make an i3 version with everything already in the unit that would maximize temperature etc. Pre-load it with Windows 8.1 and Many more low level users like my parents would probably buy.
