5 out of 5 eggsWorks

Pros: Power supply didn't explode

Cons: poor motherboard placement limits usable heatsinks.

Other Thoughts: It's a pretty solid ITX case, you can even fit a fan on the side panel with zip ties and careful insertion. I may have already reviewed though however.

2 out of 5 eggsNo Stock Intel LGA 1150 coolers

Pros: cheap, power supply (rated for haswell)

Had to stop after installing motherboard, CPU + stock cooler because the provided power supply with the case does not fit with the stock cooler. The power supply literally rests on top of the cooler no matter which way I set it.

cheap flimsy metal as well...drilled air vent in top of the case to flip power supply so it wouldn't overheat from CPU exhaust. Really disappointing because the case had such great potential.

Other Thoughts: First itx build
i3-4430 (w/stock cooler)
Required to buy aftermarket a more expensive case...

4 out of 5 eggsDecent Little Case

Pros: Small, included power supply, minimal design.

Cons: Tight space, front covers are a little flimsy.

Other Thoughts: You would expect a small case to have tight spaces, so it's not really a con. The case did its job and is working quite well. I used it in a build for my parents and they like the size of it. I finally got them away from using laptops as desktop computers. The stock cooler for an Intel APU might not fit, I didn't really try though. I used the Noctua NH-L9I and it fit with a little bit of clearance.

4 out of 5 eggsGood Bang for Buck

Pros: Size
Built in PS
Sleek Looks

Cons: No USB 3 on front panel.
PS Location.
Like other reviewers, I think this could have been mounted differently.

Other Thoughts: Used this for my first Mini ITX build for a small simple budget HTPC. Some previous reviews complained of broken bay cover doors. Mine are not. They seem to function correctly. Yes, it does have a reset button, just below power button. Has LEDs on front, but not real bright. I added a card reader to the 3.5 ext bay with USB 3 on it to get USB 3 to the front panel.

4 out of 5 eggsAlmost Perfect!

Pros: Everything you'd want from a mini-ITX chassis... good price too!

Cons: - PSU ventilation is down... literally on top of the stock CPU heatsink. For this chassis, the ventilation would have been better placed on any of the internal sides of the PSU or even the top, if the top of the chassis was also grated. Fortunately the LGA1050s run relatively cool that I haven't noticed much of an impact on heat [yet].
- Once you stick an optical 5.25 drive in and a 3.5 media reader in there's no built-in mounting room for a hard drive. This is easily solved by drilling holes and mounting the HDD [or SSD] to the bottom of the chassis (I used a 3.5 to 2.5 adapter as a template). My point here is that the 3.5 portion of the chassis could have been extended all the way to the bottom of the chassis to make more room for an internal drive.

... not enough cons here to dock this product any more than a single egg though!

Other Thoughts: This is my first mini-ITX build (built for a client). Nice solid build and I'm very pleased with the result. The only drawbacks I see are what I mentioned above.

4 out of 5 eggsGood!

Pros: Solidly built with good number of options.

Cons: Not really a con if you know what you are doing...component insertion and wiring logistic issues demand preplanning before you put this unit together! It will take you some time to assemble this case!

4 out of 5 eggsRoomy case but no clearance

Pros: Sturdy case with small power supply, lots of room for drives. Is minuscule!

Cons: Very low clearance for the CPU cooler, the stock cooler with current generation AMD CPUs did not fit, had to resort to an Akasa ultra-low profile cooler from FrozenCPU as newegg didn't carry any.

Other Thoughts: it's super cute

3 out of 5 eggsYou could do worse

Pros: -Looks great
-Built fairly well
-Cheap price especially on sale
-Comes with psu

Cons: -CPU is directly below power supply
-power supply looks like it could easily break away from the case and land on the motherboard
-flimsy front bezel

Other Thoughts: This case would be great except for the fact that is has the power supply mounted directly above the motherboard. To make matters worse the space between the cpu heatsink and the power supply fan is less than half an inch. I am using an Athalon 5350 with the stock cpu heatsink which is much smaller than an FM-1 cpu heatsink so if you plan on buying this case for a socket Fm-1 cpu think again as it wouldn't fit.

4 out of 5 eggsgood basic case

Pros: Used for my first mini-ITX build and so far has been fine. Installed a Sempron 3850, and the stock HSF just clears under the included power supply. It is a tight fit for everything, but that's kind of the point of a small case. I saw a few comments about not liking the sideways/side mount harddrive location, but I found it to be a good use of space.

Cons: would be nice to have a spot for an extra fan mount. If you don't put in any expansion cards there could be room, but other than that would be looking at a DIY type fan solution

Other Thoughts: Noticed one review that said there were no LED's or reset button, but this case does have both. I get a green and red LED that show through the front grill, and the reset switch is nicely hidden as part of the grill just below the main power button (easy to miss)

I'm not running any extra video card, or any optical drives so have plenty of room to run wires, but even loaded up with stuff the space should still be manageable. Biggest thing was to plan out the order of installing components.

4 out of 5 eggsDo not use with the 6-item combo.

Pros: Good layout. Seems to fit enough hardware.

Cons: I bought this with a recent 6-item combo deal, including the AMD A8 6600K "Black Series" APU.

The APU and heatsink that it comes with DO NOT FIT inside this case comfortably.

The PSU rests on top of the heatsink fan, high enough to lift the lid of the case and keep the case from closing.

Other Thoughts: I can recommend this as part of a custom build, it's a nice enough case for the price, but if you're considering the AMD A8 6600K Quad-core processor, make sure you get a different cooler/fan.
