Pros: If you live in a desert with low humidity, this is an effective unit. If you do not, it will still work but you won't notice as much cooling as it is in essence a mini swamp cooler and they do not work well in high humidity areas above 65-70% humidity (do some research on swamp coolers if you're not sure if you want to get this for your area). For reference, it it currently 98 outside with 10% humidity and the room temp inside is 86.0F and this unit blows out 66.4F (30C to 19.1C) - side note very easy to switch from F to C so you can pick your preferred display mode. It does not have a huge cooling area as the BTU's of heat are just too great but this unit has been a life saver when it's set up about 2 feet away. I notice the heat as soon as I get up and walk away from where it's blowing on the desk. Unit has a small footprint, easy to set up and use. Power uses a micro USB cord like most phones use so unit is portable with a power pack that can do the 2V charging - not advisable to move it while it has water in it.

Cons: In desert conditions of 5-20% humidity the water tank with full power fan lasts about 2-4 hours, which the literature the company provides says 4-6 hours on average, just letting you know desert longevity. I only list in the con section since when sleeping it will run out of water with fan at full power so I run it a 1/4 power and it usually makes it almost through the night, the indicator light when I turn it on in the morning shows that it's bone dry upon waking, but it is still an air filter even when it's dry. There is no on/ off switch; however, it is more ECO friendly to disconnect unit from power so not really much of a con. The filter does have to be replaced, it is not washable. Seller recommends replacement every 6-8 months with replacement costing just under $40 full price.

Overall Review: Ran unit dry for two days before adding water just to get that new plastic smell worked out some. Compact packaging, eco friendly came with everything needed to set unit up other than water/power. I bought the blue version and I like the color - it's a little lighter than navy blue.

Pros: Case is super silent, sturdy, overall very high quality and perfect for a high end build.

Cons: It is a fairly heavy case about 30 lbs before any components mounted, be aware of that. Doesn't come with sticker saying "Beware: Silent Killer"

Overall Review: I live in an extremely dusty climate the dust filters are awesome and I only have minimal build up of dust in comparison to what I used to get in my old case which also had filters. The two filters themselves are easy to take off and clean. Case came with one front and one back fan. At minimum, I would recommend to buy one additional 140mm case fan to go in the front panel intake and a 120mm fan (Consider your PSU size/length as you might be able to do a 140mm) for the bottom. Side panel/upper panel fans would be your personal preference. Box doesn't say this; however, it is possible with some minor tweaks to get an eATX inside this thing (recommend looking at videos before doing). Lots of room for everything you'd want to put in it. The two hidden SSD mounts behind the mobo are great. Look at some un-boxing/builds of any of the Define R-4 cases and you'll see all you need to buy this case.

Pros: Recently used this item to mount new 2.5" SSD into the 3.5" HDD slot inside of a 5 year old Coolermaster Cosmos S chassis. Sturdy design and the installation was smooth just using a small Phillips screwdriver. Would buy again.

Cons: None for me.
