4 out of 5 eggsOk

Pros: Amazing cooling options, filtered front panel, $80 piece of heavy steel. Can accommodate SSI EEB-sized mobos no problem.

Cons: Something I like to call "Rosewill quality". In about 3 of the 30-something cases I've used in builds already, there were slips through QA.

In the first one, the front panel had TWO reset switch headers with the same colored wires and labels. So I had to determine which one is power and which is reset by trial and error.

In the second slip-up, the wires for D+ and 5V (red and green) on the USB headers were SWITCHED. It's an easy fix but a mistake on Rosewill's part nonetheless.

The last defect I've come across this afternoon was a bent IO shield holder (back panel). It was bent in such a way that the IO shield would not fit properly into it (the IO shield had square angles, while the Rosewill case was skewed).

That's 3/30 that I've built so far, which is a decent 10% failure rate, but this cannot continue to happen. It hurts productivity and costs us money to replace or return.

Other Thoughts: I'm turning the third defective case into a coffee table or a wall-mounted bookshelf. Because Rosewill quality.

4 out of 5 eggsGood for the price

Pros: I have built 3 systems using these cases so far. They are good and fairly flexible for the price point. The price is a excellent and the layout is good. The fans are a plus and a minus. They're good enough and fairly quiet. See the cons for the minus.

Cons: The negatives to this board come as a result of the price. It is NOT a $1k case, so don't expect it to be.
1. The build feel is cheaper than expensive cases.
2. The hard drive mounts are CHEAP and probably won't last a lot of taking in and out. But again, the price is the determining factor here.
3. The design of the front bays doesn't work great for 5 1/2" DVD drives, Its just not great.
4. The screws that attach the top of the case are on the side so you cannot take the top off while its in a rack--just a poor choice. Not sure why on this one.

Other Thoughts: Buy this case with confidence that it WILL WORK, just understand the limitations. I give it a 4 egg instead of 5 simply because I think some decisions they made could have been made better and still keep the price where it is (like the screws for the top).

4 out of 5 eggsbasic and sturdy

Pros: Very sturdy, versatile, and spacious. Outstanding value for the price. I was able to fit it with an Asus P9D-E/4L sporting a Coolermaster Hyper N 520 with no trouble, though the stiffener rail needed to be relocated to its forwardmost notch. Fans are smooth and quiet (for a server). Fit and finish are surprisingly good for this price. Airflow is excellent, and it would be easy to fabricate a custom air duct for this case if required.

Cons: The design is adequate, but unlike the two Rosewill workstation towers I own, this one is not at all elegant. The complaints about the design of the drive trays are definitely valid, and are a real disappointment in comparison to the slick ones in my towers. The molex fan connectors are clunky and cumbersome, though the fans themselves are ok. The chassis cover's tiny screws are annoying. The air filter in the bezel is just for show; it's very gappy. I removed the whole pointless bezel. This chassis does not include rack rails.

Other Thoughts: If you don't need frills, don't mind some one-time hassle, and appreciate substantial construction with ample versatility at a good price, this is your chassis.

5 out of 5 eggsThis Case is HUGE !!!

Pros: 8 HD cages with their own fans 3 5.25" ,nice touch for Blue burner
extra 3 fan bar for the middle of the case. a great DIY'er .
you will not want to lift this case around too often.

Cons: molex ! molex ! ----connectors out the ying-yang. All from the fans 7 total, has to be a better way, I ended up stripping the wire and soldering the ends together

Other Thoughts: get rid the the PITA plastic hard drive inserts go back to old fashioned screws.

5 out of 5 eggs

Pros: Huge case, a lot of space, everything fits really well. You get a really decent case for the price.

Cons: The most annoying thing about this case is the hard drive bays. They include those cheap plastic sliders with screws covered in rubber, which doesn't want to stay in the sliders and it's really hard to put an hard drive in. Would be better with simple screws.

4 out of 5 eggsGreat case!

Pros: I like this case. It's surprisingly quiet with all the fans in it, but I suppose that's to be expected with 120 mm "dumb" fans. They move plenty of air and there is some noise, but it's more from the volume of air moving in/out of the case rather than the fans themselves making noise.

Also, the cover of the case is pretty easy to get off, but it's held on by regular screws. For the price, I suppose I can't really expect a screwless design.

Cons: The drive cages are cheap, the plastic brackets and pegs that fit on the drives to insert them into the cage don't line up properly with standard holes, it's a very tight fit and the rubber vibration insulators get pushed out and make it difficult to get the drive into the cage.

Other Thoughts: It would be great if the three 120 mm fans in the middle of the case were on a removable bar. There's a removable aluminum bar that I suppose is there to give the case some stability, it would be nice if both of them were removable so you could get to the connections on hard drives easier. The way it is, I have to slide the drive cage part-way out the front of the case so I have enough room to get my hand in there to plug in SATA and power connections.

5 out of 5 eggscheaper simpler... predecessor of the L4500

Pros: This case, when used with the RSV drive cage, can hold 12 hard drives with excellent airflow/cooling. Some of the other reviews have suggest that removing the power/reset/front-USB module is required to place the third drive cage---this is incorrect. The third drive cage simply gets installed rotated 90 degrees and the case has all the detents set up for that to work smoothly. The updated L4500 places the module on the side so all three cages line up. There's plenty of internal room for a full size motherboard and power supply and lots of fans, and the entire front panel operates as an air filter to help keep the contents clean. If you want to, instead of a third drive cage, you can have 5½ inch peripherals placed horizontally such as optical drives.

Cons: The tool-less drive cages take some fiddling to work but are serviceable. Early versions had front handles that go beyond the 4U standard envelope -later versions fixed this. The RSV drive cage sometime goes out of stock, and several other drive cages I tried from other manufacturers didn't fit well - Rosewill once rounded up some cages for me when I couldn't order them [THANK YOU!].

Other Thoughts: The updated L4500 holds 15 drives, has better drive cages that are easier to load with drives, and fits the three cages in the same orientation, and comes with all three cages included. If you have no need for 5½ inch peripherals, the L4500 works out better than this L4000. I actually mixed the drive cages of the L4500 with two of these L4000 and two RSV cages to get three boxes that held 13 drives each - I had the L4000's in hand when the L4500 became available.

The R4000 is more compact because it lacks the middle fans, but it's otherwise similar and uses the same drive cages as this box.

There's other boxes that can hold twice as many drives in 4U, but I've had failures of the mezzanine boards that connect the drives and trouble getting stable controllers for 24 drives under Linux. I can get stable RAID systems with 12-15 drives using motherboard SATA ports and simple SATA add-on cards.

3 out of 5 eggsNice case with some quirks

Pros: Nice large case, sturdy. Plenty of room to work inside. great price for a server case. Comes with plenty of fans, two in the rear, two in the front, three that reside inside the case behind the drive bays. Runs rather quiet.

Cons: What I don't like is the hard drive carriages. They are cheap plastic and provide 4 cheap white pin plugs that hold in the drive. I had to use traditional screws. I had a difficult time lining up the pins to the drive. Then they would pop out and the white grommet would just deteriorate.
The Instructions are basic, small print and rather useless. But the case is simple enough, you can figure things out.
The front door on the case.....would be nice if you didn't have to lock it all the time. If its not locked, it just slams careful!

Other Thoughts: I think if Rosewell can re-think the cons, you would have a great server case. They may be more annoying to me only, but in general, I can purchase ATX case for the same cost that have better functionality.
