4 out of 5 eggsGreat price.

Pros: Great Price. Lots of space. I am currently running a linux server using ZFS with 5 WD 3G enterprise HDDs leaving lots of room for upgrades.

Cons: Access to backplanes is tight and removing the mid fans is a must for connecting both the power cables and the SAS cables. Newegg discription is a bit confusing (see other thoughts) this is why I only gave it 4 eggs.

Other Thoughts: I was a bit unsure what to expect as the overview page states SAS (II or III) @ 6G but the specifications page states SAS (I or II) @ 3G. This must be an older model as it is actually only SAS (I or II) and does not have the redundant power connections (only single connection per backplane). Given what I paid for this case, I was not too disappointed about it being an older model.

5 out of 5 eggsGreat case for cost

Pros: Very cheap 20 bay case. I have been using it to run a SAN for esxi. Backplanes work great with lsi 9260-4i and an intel sas expander.

Cons: Wish the bays were made of metal and not mostly plastic.

Other Thoughts: Compared to other brands that want $1,000 - $2,000 for a case like this, this case is great for the money.

5 out of 5 eggsAwesome!

Pros: Room for 20 drives, 2 SSDs and 1 CD/DVD Rom.

Was shipped double boxed and everything is awesome. Plenty of room for everything.

Cons: Even though there is room for everything I found it easier to take out the middle fan rack to access the power supply and SFF-8087 bottom connectors and then put the fans back in.

4 out of 5 eggsBuild an HTPC on steroids

Pros: 4U chassis, easy to work with, 20 drive bays, layout, solid construction, rack mountable, good use of space, can use large PSU without issue, full-sized ATX, front handles make relocating it easy (if lifting a ton of drives is ever easy).

Cons: Super noisy case fans (replaced immediately with much quieter models), flaky wiring and board for the front switches, mounting for slim optical drive hard to work with, should have included the necessary MOLEX multipliers.

Other Thoughts: I put a Gigabyte Sandy Bridge board in with an i3-2120 and 8GB of RAM. OS resides on a 120GB SSD. Four cheap 4-port SATA cards add to the built-in 8-ports on the motherboard to feed all the hard drives, the SSD and the optical drive. Each tray is loaded with a Seagate Barracuda 3TB 7200 RPM drive (NAS drives were far too expensive when I built it), which I will replace with 4, 6 or 8TB NAS drives when I find the money to do so. Everything is working together in harmony under the Windows Home Server 2011 installation with DriveBender software adding back in the pooling technology the misguided nimrods at Microsoft left out. The Gigabit Ethernet port is connected to likewise switches on the router and my network allowing multiple simultaneous streams to run through the house to computers, media players and tablets. That is 60TB of data available at any time. LOVE this chassis. Worth the investment (granted I got it on a wicked Christmas sale in 2010 that included free rails and free shipping for about $250).

4 out of 5 eggsVery Nice

Pros: Low price for what it is. Compare to hot swap bays that take up 5.25 bays and convert to four or five 3.5 bays and you come out way ahead with this. In my home file server, I wouldn't even consider mounting the drives in anything other than one of the hot swap cages; with a RAID, there is too much risk of accidentally pulling out another power cable or whatnot when adding the new drive (or removing a failed drive).

The cooling is very nice as well. Everything is kept to a good temperature.

All the drive bays have their own activity light (useful for finding a drive).

Despite what it says, you can mount a 3.5" OS hard drive inside the case.

The case I received has USB3, which isn't listed in the specs.

I tested all the drive bays and they all work.

SAS cables are a godsend, I truly cannot imagine having 20 SATA cables streaming through any case. 5 SAS cables to RAID cards (or in my case, 4 SAS cables to two RAID cards and one SAS->SATA cable to my motherboard) is really the way to go. Makes everything much much easier to manage. The previous drive cage I had was a massive PITA to deal with because it needed 5 SATA cables going to it and two Molex connectors.

Cons: The case I received does NOT have redundant power connectors. One of the reasons I chose this case was the redundant connectors. Not really a deal breaker, but since this case also has USB3, it's clear there is a new revision of the hardware that Newegg isn't taking into account.

No instructions for anything. This isn't really a big deal for the motherboard mounting or using the drive cages, but when you want to start adding the OS drive (assuming you're using a supported 2.5" drive or mounting the DVD drive, it gets a little tough until you figure out how it all works. Not a big deal, but still seems bizarre. Personally, I used an old external USB DVD drive I had laying around and yanked it out of its enclosure. Fits perfectly. Then, I just connected the USB cable to the internal motherboard USB headers (the drive itself didn't have an adapter on it like I had initially expected).

The top two rows of drive bays are a bit to snug, the drive trays stick a little bit. Once again, not a deal breaker, but still a con.

Other Thoughts: I've seen people complain about the noise this puts out. It's really not that bad. I mean, it's way too loud for a bedroom or living room (where some people were putting it), but for its intended audience, it's not bad at all. I'd prefer the fans to be loud over potentially 20 drives overheating. I keep it in a room we don't use often and when we do, the noise isn't bothersome in the least.

None of the cons are a big deal, this case it really pretty great, especially for the price. Most everything is simple and easy to figure out even without the instructions. SAS cables make everything easy.

It would have been nice to have the redundant power supply connectors, but I'll deal. Truthfully, I've never had one of those connectors ever break or the cable from the PSU die, so it's probably not a big deal.

Highly recommend.

4 out of 5 eggsGood for the price

Pros: 20 3.5" SAS/SATA Bays. Good interior volume to work. Not so cutting edges.

Cons: Does not come with dual molex power as stated, but I won't use them anyways. My biggest issue is the opening for the SAS cable is about an inch off and the connectors on the backplanes are right across the fan, making it uncomfortable to plug the SAS cables. NORCO's website had a different picture, making you think that all is good.

2 out of 5 eggsNo support

Pros: Great price for a 20 bay rack mount case

Cons: No documentation, No support

Other Thoughts: I bought this case last in April of 2013. I've only just gotten around to populating all of the bays. I've discovered 3 of them are failing. I've tried contacting the manufacture by phone (No answer ever) and by email (No Response). Guess I'm stuck with an 85% functional case.

5 out of 5 eggsCan't go wrong

Pros: Number of drive slots in this chassis is fantastic. And the fact that it uses mostly standard parts (especially the power supply) is a big plus. Cooling works well.

Cons: Connecting to the backplane can be challenging, but it just takes some patience.

Other Thoughts: This is a fantastic basic server chassis. For the price it can NOT be beat. I was skeptical at what I'd get for what I paid, but I was very happily surprised. This thing is built like a tank! Plenty of room to put whatever you want in it. The 2 additional internal drive slots makes it perfect for a NAS (I use FreeNAS on this box).

I expected something a lot louder as well, but it's surprisingly quiet.

5 out of 5 eggsGreat FreeNAS/NAS4Free Box

Pros: 20 drive bays
Additional bay for slim CD/DVD, internal bay for hard drive / SSD. Edges were pretty smooth, no cuts. Box feels very sturdy. holding it by the handles did not feel like they were going to break. All backplanes worked as they should. Drive caddies are very rigid for how light/thin they are. Supports standard power supply.

Cons: You have to unscrew 10 tiny little screws to move the fan-wall that partitions the component area from the HDD bays. This is required if you want to hook up the power and SAS cables. Seriously though, that was the only real negative I could find.

Other Thoughts: The case is rather large when you look at it externally. Not too wide, the main case is 17.25" wide, the faceplace with the flanges to rack mount it are wider. The case is about 25.5" long. Seems big, but once you have it open and start putting in your stuff. It's not all that big. I have a mATX board in, and I had to find a place to mount an Intel SAS expander. Not a con, just something to consider. Otherwise my FreeNAS build is working very well. My config is

GigaByte AMD Mainboard
Athlon x2 3.4Ghz
LSI 9211-8i SAS controller
Intel SAS expander
750Watt Modular Power Supply
4x3TB HDD (RaidZ1)
4x2TB HDD (RaidZ1)
4x1.5TB HDD (RaidZ1)
4x400GB HDD (for testing)
