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.

4 out of 5 eggsBox

Pros: -small (for a server)
- front 5.25 bay for me to pop in a hot swap bay
-front usb that is shielded from dist
-rubber feet
-included PSU

Cons: -Big for a shoebox I guess
-sideways mounting of the hard drive is very awkward
-bottom bay cannot be used as additional 5.25", even though the door is 5.25"
-if there is a HDD LED, it does not work
-no reset button, only power
-no power LED/non-functional
-no fan mounting other than PSU

Other Thoughts: I use this case to house a home Debian webserver, so the lack of LEDs and a reset button is really a non-issue for me. The size is also actually a benefit for me as it gives my drives more breathing room. I would suggest however that in future models of this size that the bottom bay just be a 5.25" bay with an adapter. The bottom bay just feels like a waste of space only letting me house one extra hard drive when I could be using a backplane. Even one fan mount would also be really nice, I ended up hot gluing a fan to the left side and it really keeps the temp much lower.

4 out of 5 eggsToo darn BIG

Pros: The case feels sturdy, and is very affordable. I like that it has a 3.5" bay that I can toss a card reader in. It has plenty of room to work with.

Cons: This is where some of the reviews are driving me nuts. This is listed as a mini ITX case. It is supposed to be small. My complaint is that it is huge for my purposes. I didn't realize just how large this case was until it showed up. I sincerely should have bought a box with half the space. I feel like I bought the the parts for a nice small form factor device and now I have something nearly as large as a regular desktop. If I were not so cheap, I would buy a smaller case. Live and learn.

Other Thoughts: It really is a nice case overall, which is why I am giving it four eggs. My rant was geared more towards those that complain about the case size. It is for a mini ITX mobo. Most cases for this would be smaller.

5 out of 5 eggsBetter than expected

Pros: Price, $45 with power supply, how can you go wrong.
I'm using this with a i3-4130 Haswell with stock cooling fan. Had to nudge up the power supply slightly to get mobo and cpu under it, but it fits in there nicely.

Also using MSI B85I which I'm also impressed with, zero issue with it as well.

All metal construction, very solid. I'm not using any optical drives, wish Rosewill would offer a non-bay version of this as it would easily chop another 2-3 inches off the front of this thing.

Really like the side mounted hard drive slot.

Cons: No Cons

Other Thoughts: Using this for the kids room for web based games and streaming medi, netflix, a-mazon and hulu (we don't have cable). Haswell on-board video is more than adequate.

5 out of 5 eggsWorks

Pros: Fits together nicely, holds components with plenty of room and ventilation.

Cons: The LED's are quite hard to see from an angle. Not really that big of a deal, but with a quiet system that runs without a monitor, it can be hard to tell if the system is on.

Other Thoughts: When assembling, some parts block other parts, so it takes a little bit of planning to make sure a component isn't covered.

5 out of 5 eggsTight spaces

Pros: This case was certainly an upgrade from the cardboard box my HTPC was in before this case. The power supply seems to work well with my build and is very quiet.

One of my initial concerns was with the door in front of the optical drive bay. Turns out there was no need to worry. The door has a button that reaches in to the button on the drive itself and the case includes little spacers that can slide a little to get it to push right where you need it to. So long as the button is on the right hand side of the drive.

The other little surprise was the rubber feet that are included. There are slight markings on the case to mark where you can place the rubber feet. You can either place them on the side or the bottom.

Cons: One of the drawbacks was how tightly packed the case was. It was a bit of a challenge to get the SATA and power connections onto the back of the optical drive with the power supply so close. But it was workable. If you have right-angled connectors, it will make this part much easier.

The other drawback (and some may call it a pro), but the LEDs for hard drive activity and power are very faint. You have to be looking directly at it and from somewhat close distance to see them.

the final gripe I have is with the optical drive door. When the drive is open, you cannot press the button to close the door. You will have to gently push the caddy in till the drive closes itself. Not a big thing, but it is a little annoying.

Other Thoughts: Overall, great case and I am very happy with it. The 3.5" bay worked out great for a card reader/usb3.0 port connection. A full size hard drive could be mounted inside, and it looks like I could even squeeze a graphics card in there if I decide to upgrade.

5 out of 5 eggsNice! Small and well thought out.

Pros: While it is small, it's easy to build and still holds a full sized DVD player. It's VERY quiet.

Cons: None that I remember.

Other Thoughts: With all mITX's, you're going to want to use SSD drives.

5 out of 5 eggsEngineered very fine

Pros: Seems pretty sturdy
Has logical part placement, if you read the manual

Cons: Reset button doesnt work, but I'm pretty sure I just plugged the wire into the mobo wrong.

Other Thoughts: For this price you will find nothing better

1 out of 5 eggsDoors don't close

Pros: Cheap. Includes power supply.

Cons: The tray doors do not close. I purchased 5 for small form factor office PCs and every single one hangs open and ends up getting broken off.
