Good for airflow and cooling, bad for dust getting in
929589
Gave me the better air flow I was looking for.
The holes are a decent enough size that it takes awhile for dust to block them.
The downside is they let dust in...
But it did give my rather closed up case some much needed air, and I am several degrees cooler now.

PROS:
-Mesh front design great for airflow.
-Lots of mounting holes on side/top for additional case fans
-Bottom mount power supply
-Internal drive bays face the side for easier hookup.
-FRONT USB 3.0 w/ audio jacks

CONS:
-Power Supply is NOISY!  I replaced with a CORSAIR CS450M after a week, now it is quiet.  Logisys PS fan runs at MAX 24/7!
-SATA power cables too short to reach from CD-ROM drive bays to hard drive bays
-NO 8-pin ATX power for newer MOBOs (again, PS is weak point! but expected at price)
-Power button a little tricky (takes momentary push to turn on)

UPDATE!  After a week of use, included case fan became noisy, replaced with ARCTIC F12 PWM.

The noise level is what I expected it to be, and they do move a lot of air. I have mine mounted to the top of a Cosmos S case, and immediately below the top is a 120mm by 360mm radiator taking the coolant from my SLI GTX 770 hydrocoppers.
They didn't drop the idle temperature any, but high stress temp did drop by 10-15 degrees F, so they are quite effective.
The problem is that when the fan chassis heated up it warped just enough to make all three fans buzz a little, one right away, the others after a few days. I was able to counter this by gluing about an ounce of 1/2 washers to the center of each fan. Hopefully they don't warp anymore with use.

The Good:
-Multiple connectors
-Low RPM
-Moves a lot of air

Nothing bad to report

I bought this fan to keep my ITX computer build running cool and quiet. I had to sacrifice the 5.25" drive bay because this fan is not small. It was kind of over-kill but I'm very satisfied with it. When I install it as an exhaust fan, it's quiet but does not cool as well as when I push air into the case. Seems like it would be the other way around. Exhausting it dropped normal operation from 49 degrees C down to 40.

  I turned it around and created positive pressure in the case but I could hear it. I'm sure that's because it's small inside with a lot of obstacles. It's not loud or anything...sort of a low drone that doesn't change. I really don't notice it. But I did notice it ran 5 degrees cooler! I mean the CPU seldom reaches 40 degrees. I don't have a big graphics card so maybe that's partly why. The more I thought about it, the better I like it pushing air in. For one, it's got a matching filter (separate purchase) so I won't be pulling dust in through every crack and crevice. Secondly, It aids the power supply's exhaust fan. Now, the CPU cooler fan and the PS fan never change RPM. Quiet...steady...cool. I'm happy with this purchase.

I like the case. It looks nice and provides excellent air flow. The large window in the side is nice. The cable management options are great. Makes it a bit tough to put on the cover for the case, but it really helps to clean up the inside of the case.

My biggest problem with this is that it's not wide enough for the cpu fan I originally wanted. I had bought the hyper evo 212, but like I said, the case want wide enough. I ended up going with the cooler master hyper tx4. The case was still not wide enough however, and I had to remove the (140 mm) fan in the window to make room for the cpu cooler. Not to much of an issue since I planned on doing that to begin with, but still inconvenient.

Other than the overall width of the case, it works fine. Has great airflow, high visibility, kids good, and good cable management. Definitely exceeded my expectations for the price. Would recommend.

Having three fans is a perk.  But all and all.  This is a really bulky design.  And really steep.  My laptop has a habit of sliding all the way down on this.  But the three fans do keep my computer cool!  I should have researched this out more before I bought it.  Something smaller, and sleeker.  More meant more one location, not to travel with you places.

I bought two of these, and they look really nice and appear to be quality manufacturing.  However, if you're going to be running any intensive applications such as emulation or Kodi on your Pi I'd recommend a different case.  Even with heat sinks both of the Pi 3's I installed in these gave thermal warnings.  They appear to be well-ventilated at a glance, but the problem is that the bottoms sit directly on the surface of where you sit it, not allowing enough airflow underneath to properly reach the ventilation holes.  Adding rubber feet on the bottom to raise it a bit might help, but mine didn't seem to include them.  Otherwise these cases look great.

Love the airflow with this case and the flexible internal configuration. I had some static issues, though. My cat rubbed it's face on a USB port (with a wireless adapter in it) and the computer died. After many hours of diagnostics and one new CPU, the computer is up again. Still, if my cat rubs up against it, the computer locks up.

Update: Turns out that during install of PSU, one of the front panel block pins got bent (where you plug in the HDD light connector). I straightened it and reseated the reset button connectors and no more static problems...

They get the job done as another reviewer said. They have decent air flow and they look nice but dang do they get LOUD.

I wish I had done a little more research before buying these fans. I'll go through the pros and cons

Pros
-Look nice
-Decent Air flow
-Rubber mounting holes
-Cheap double pack

Cons
-LOUD
-Not as much static pressure or air flow as Noctua NF-F12 or even NF-P12
-Not PWM

I bought these because i've seen a lot of great builds with them. Over time though I realized that by the time I got them down to a proper RPM for the sound they put out I wasn't getting as great air flow as the specs has promised. On top of that they aren't PWM so controlling them has its own challenges for noise.

If you want decent fans (these aren't crappy fans) then get these. If you want less noise and more performance get some Noctua fans.

So the stock fans on these cards, frankly, are terrible. What they ARE good at is keeping the VRM cool because they feature a completely copper plate covering all of the voltage components. I went out and bought a Arctic Cooling V3 cooler and it keeps the ram and gpu coolm but not the VRM, well, not AS cool as the stocker. Keep in mind, however, that the stock fan sounds like a jet engine when you go past 50%, and while it cools it alright, you will regularly see 90C+ temps. I never go above 60C now, though.

Poor cooling, had to return it.  Got this one instead: https://www.amazon.com/gp/product/B0028AYQDC/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

Even with good fans the front case design hampers air flow. good for low powered systems on using a 80mm AIO. I wouldnt put a high end gaming pc in this case.

restrict the air flow more than i like. I was planning to use this as a prefilter for the room HEPA filter.

I needed an alternative solution...  the unit works great but make sure you know your airflow management. Its a great part in that, it can fit in a pci slot, without bulking up space. My unit came with a bracket slightly angled, which was great since I needed the angle towards the  cpu area and the gpu.

In any case it works better if you have fan splitter system. I am ok with it.  Not sad or happy because  as a build my chassis was the wrong pick, but the GELID fans are really great, it takes the life out of the other fans I have incidentally.

But be sure to buy your own splitter , the splitter provided by the kit can sometimes be off, or quality control  would just chuck in whatever it had.

I would concern with the vents on top that too much dust would fall into the system.  I like the idea of the heat venting up and out but how it is implemented I think will be a problem.  I would suggest redesigning the vents so they spit the heat up and out to both sides like dual exhaust. But leave the top largely covered

It's a great filter, but fits horrendously over the PSU and the rear fan. The rear fan filter doesn't contour to how the case protrudes, and for the PSU... Apparently they forgot that PSUs have cords that have to plug into them...

I am very satisfied with the quality of these Silverstone Tek 120mm Fine Fan Filters, since the installation of the fan filters (which was stupidly easy) the amount of dust in my system has dramatically decreased. I have to clean the inside of my desktop significantly less.

The only downside I can see is the fan filters are restrictive on airflow, which is expected.
