4 out of 5 eggsThis Case is worth it's cost and not a penny more.

Pros: Roomy, Lots of cooling fan mounts, solid for the price.

Cons: The included drive cages.
Tiny screws

Other Thoughts: I purchased this to house my upgraded unRAID server. Based on a pretty much universal disdain for the drive cages, I also purchased a pair of iStarUSA BPN-DE350SS trayless drive cages. I did for the fun of it try to mount a couple of old 3.5" drives into the rosewill cage, and was unsuccessful. The iStarUSA cages mounted without issue.

It helps to remove the center fan plate, but be careful with the small screws, they're easy to lose, and I imagine could easily strip the threads in the case.

Overall for what I paid for it, I'm happy with this case.

5 out of 5 eggsAwesome rackmount case for PC

Pros: - Longer then most
- Lots of fans
- Modular
- Very good for gaming PC

I was able to mount my dual fan liquid cooling system to the center rail that already has fans, so i have fans on each side of my liquid cooling!

Cons: This is my second rackmount case, and I just finished building my PC in this new case, mounted my rails, and then as im sliding it into my cabinet it stops short... I dont know if this was intentional or a mistake, but it does not make sense to me unless Rosewill has propriatary rails. The handle hardware is mounted in a way that prevents the rails from being mounted all the way up to the front... so it does not slide in all the way! there must be a rail that allows this, otherwise you cant even screw the cabinet mounting ears on the case to the cabinet...

Other Thoughts: second rackmount case, first was too short making my gaming pc too crammed, this case allows for more room for larger video cards.

2 out of 5 eggsDecent for the money, bad QC.

Pros: -Huge, can hold just about any mobo less than 12x13"
-Removable HD trays
-Rails for cable management

Cons: -Components such as power, reset, hdd activity light are wired super cheaply (understandably at this price point)
-Two of the fans that are on the 'divider' between the motherboard side and the harddrive side could not be connected via molex due to super cheap pins bending
-One of the rear fans was missing a fan blade making it useless

Other Thoughts: Other than the horrible wiring and fan issues this case could be worth the 89$ price tag. But the time it took to fix these issues made the case a nightmare and not worth the cost savings.

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.

Edit: If anyone needs a decent rail option for this case, DO NOT BUY THE RAILS FROM ROSEWILL. The Rosewill rails built specifically for this case do NOT fit properly and will hit the handles, causing the case to stick out from most racks when completely and properly installed. You will have to cut out part of the rail bracket to fully insert the case into your rack.

Instead, buy this: iStarUSA IS-26 Sliding Rail.

Works like a charm and will solve all the problems associated with the Rosewill rails, plus cheap to boot. The only mod you'll have to deal with is enlarging the mounting holes with a drill if your rackmount holes are larger than M4 screws can accommodate.

1 out of 5 eggsCan't Suck Enough

Pros: I don't think there is any

Cons: I bought this to upgrade my FreeNAS computer. Started out taking the lid off and one of the screws was stripped. Installing the stand off for the MB, one of the holes had no threads or something. The stand off sort of screw-ed in but is stripped. Connectors on the fans are cheap and the pins won't stay straight making it very difficult to plug them in. Getting the front cover off to clean the filter is about impossible. Once a drive is installed in the plastic carrier, it is very difficult to get it back in the carriage. The handle of the carrier is in the way to connect the hard drive cables. If in the future a drive is added, everything will have to be disconnected to get the hard drive carriage out to install the new drive. Just a flat out poor design. I really wish Fractal Design made a rack mount case.

5 out of 5 eggsAwesome Chassis

Pros: this chassis fit my mob perfect. No modification require. Number of fans and airflow is great. Easily modify the location of internal drive bays.

Cons: None

Other Thoughts: Would have been nice is the 5.25 bay to the far left was positioned in the same direction as all the other bays. Other than that it's a great chassis.

1 out of 5 eggsI must be used to OEM server cases

Pros: It's a metal box that holds computer parts

Cons: The way it holds said computer parts is deeply flawed
It's the worst case i have ever used.

Other Thoughts: I really don't like it, it's very hard to use.
To remove the hard drives, you have to remove the top cover, 4 screws, remove the fan assembly, 4 more screws. then tug and pull at the plastic drive bays, because when you inserted a drive into the plastic caddy, it made the caddy larger than the drive bay can fit.

2.5" HDDs don't fit at all, it's really not hard for a case manufacturer to drill 4 holes in a plastic bracket for 2.5" HDDs

The fan connectors are all molex connections that have pins that don't seat properly and fall out all the time, making them unreliable and unsafe if they fail.

Inserting HDDs causes the entire fan assembly to fall out of the case

The 5.25" drive bay cover falls out constantly, there doesn't seem to be any way to secure down any 5.25" drive with screws so it's free to move around as it wishes.

1 out of 5 eggsDecent case with major flaw

Pros: The amount of fans this case is capable of holding is quite substantial. I've had zero problems with keeping some very flimsy heatsinks cool.

There's also plenty of space to work with.

Cons: I purchased this case with Rosewill's RSV-R26LX rails. The case does not slide all the way back because it is hitting the mounting brackets for the handles. The handles now stick out just far enough (about half an inch) to keep me from closing the rack's door.

Other Thoughts: Does this case come with lower profile handles? I won't be happy if I have to pull the handles / front cover off to make this fit the rack. I'll be more then happy to change the rating if I can find a work around...
