Spacious!

Pros: +Quiet +Cool +6TB
Cons: -None
Overall Review: I've had 5 of these running problem-free in a Synology 5-bay NAS since 2014! Zero errors, zero problems.
Weak hardware

Pros: Fast, good compatibility
Cons: Power button broke randomly (with no human interaction)... now only duct tape and a hard object keep it turned on...
Overall Review: Worked great while it lasted, randomly died, though (just like my RT-N16 did...)
Second time's a charm!

Pros: +Cheap(ish) +Capacity +low profile
Cons: As with all the machines I build, I do a thorough memtest86 run against them before even adding HDD/SSD and installing anything. Right off the bat I knew something was wrong when I started getting freezing, errors, etc. from these sticks. I think this is the first time I've ever had RAM fail memtest (first for anything, I guess)... I've RMA'd them back and will see if the replacement kit is usable...
Overall Review: Update (7/1/16): Replacement kit arrived and has passed Memtest86 v7 with flying colors (even the 'hammer test'!)... looks like I just got a bad kit (which happens, admittedly). I'll up the rating to 4 eggs, but I'll dock one for getting the first bad stick of ram I've ever gotten :) Motherboard: AsRock Exreme4 mATX + core i5
Get it.

Pros: +Dead-silent +Low-profile +Keeps my 65W TDP core i5 extremely cool (30C max) +Easy to install
Cons: -Not a thing
Overall Review: I was shocked by how good this air cooler was... I have a closed-loop cooler in my gaming rig and this thing blows that away... I may have to switch that rig over as well... The only question you should have about this cooler is if it will fit in your case or not ( which it almost certainly should). Pay attention to RAM slot blockage when installing (just be sure to orient it in a way that works).
Impressive

Pros: +Plenty of room. +Very high quality construction. +6X 5.25" external drive bays +No frills
Cons: -2X 80mm exhaust ports (they could've gotten away with 2X 92mm probably). -The power LED connector is a three-prong style, incompatible with a lot of motherboard headers (I had to get the pliers out and 're-assign' the offending wire :) )
Overall Review: This case is a joy to work with. The 6 5.25" bays allow me to have two 4X 3.5" -> 3X 5.25" adapters for two 4-drive RAID arrays. The additional 3.5" bays allow for system drives as well. The power LED thing was a bit of a bummer, but easy enough to fix (This is with an AsRock Extreme4 mATX board). Plenty of room inside when dealing with mATX/mITX. Plenty of room for a dual-fan Noctua NH-L12 installation, as well.
Perfect

Pros: +Quiet! +Moves a surprising amount of air. +Fits easily inside of a 4U server case.
Cons: -A bit pricey (but worth it)
Overall Review: Paired two of these up in exhaust position in my 4U rack-mount server case. Absolutely can't hear them spinning and the air circulated is impressive.
