4 out of 5 eggsGreat Server Chassis for the Price

Pros: - Easy to work with and good amount of space for components

Cons: - There is no 2.5 inch drive bays so if you plan on using an SSD you need to buy a 3.5 inch to 2.5 inch adapter
- Since the power supply is mounted on the very left of the case, you will most likely need a CPU and motherboard power extension cables

Other Thoughts: - The chassis has USB 3.0 and the fans are 3 pin PWM connectors instead of MOLEX connectors even though the pictures do not show them at the time of this review.

4 out of 5 eggs

Pros: inexpensive. small. well-built for the price.

Cons: case design & assembly make fan replacement a tremendous pain to do. power led seriously too bright, hdd activity led too dim.

Other Thoughts: * VERY IMPORTANT WARNING * if you plan to replace the stock fans, be aware that they are not 40mm fans despite what the manufacturer would say, but rather 50mm fans.

furthermore, i had to dismantle the case more than i would have wanted to do this (replacing aforementioned fans). i haven't found a way to simply unscrew the "plate" that holds the drives and the fans; i had to remove the front of the case (incl. removing the handles, which are clearly not intended to be taken off repeatedly) to be able to perform the swap. do this before you put the motherboard in the case and make sure you have to do it as seldom as possible. norcotek, please change that design point, or at least let us know how to take the case apart.

other note for norcotek: i'd actually prefer to see see a pair of (easily changeable) 80mm fans instead of 3x50mm ones.

this is the first power led ever that i find too bright. i had to use one nic/alert led for hd activity, as the one for the storage is simply not visible when power is on. considering what i perceive to be the market for this case, the network activity leds could be dispensed with, and the hd activity led moved away from the power led.

on the unit i received (march 2016), one of the 2 usb ports on the front is a usb 3.0 port. nice touch.
i also appreciate the exposed 5.25" bays, it let me put in an optical drive for os installation or for running a live-cd.
the case is quite sturdy, even if the front handles are plastic. for a low power usage, low-heat rackmount device (pvr, etc.), this case is pretty good choice, despite its foibles. i know i started the review negatively, but ultimately do not regret this purchase.

5 out of 5 eggsExcellent case...Fans leave more to be desired

Pros: -Strong thick case, Does not feel cheap
-IO lights for multiple NICS (Though requires the hardware)
-Fans included
-2 - 5 1/4" bays
-Supports ATX PSU
-Fits an MATX and ITX
-Short and compact
-Locking mechinism on the bays is awesome
-HDD dampening for 3.5" HDD bays
-Looks to be a full length card slot at the top of the case over the mobo. would be great for a single slot GPU for visualization, or a 4 port NIC/SATA controller card

Cons: -Fans wires aren't spun, sleeved or bonded so they have to be cable managed or twisted to keep the individual wires from ending up all over. Easily fixed just annoying, either get new fans or twist/cable tie the wires.
-Removing the fans is a pain, gotta take out the handles, and the front panel. This wouldn't be an issue if they were decent
-This one is more just cause of my build, but a regular (top fan) PSU doesn't have anywhere to breath. Should put a little venting at the top. I'm sure most people that would look at this case are just trying to rackmount a system they built for cheap.

Other Thoughts: I would buy this again. I'm using it for an unRAID setup with my media server. I use a 4-2.5" HDD hotswap bay and the included 3.5" HDD bays and it's great for what I use it for. I don't have to get an expensive deep rack just a cheap cabinet works. I also had to get a blower fan setup for the 5.25" bay, but thats just to ensure great cooling as I don't have it in a fridge. For a 2u case at a great price its amazing. The quality is top notch, the ability to expand is great. The flaws are just little things, I saw a review of the older model with the front panel sticker over the power/reset button issue was fixed so they are paying attention. Good Job Norco, I love your product.

3 out of 5 eggsSolid case but many annoyances - NOT 40mm FANS!!!

Pros: Solid construction
Plenty of space

No frills but the case does its job just fine.

Cons: Replacing the fans is a tremendous pain, I've never had to undo so many screws just to get at some fans. Plus the fans are junk. They work but they're loud and within a few months they started making grinding noises.

The description is incorrect regarding the fans. THEY ARE NOT 40mm FANS!!! I read everything and ordered some 40mm fans to replace the 3 in the case and when I opened it up I was surprised to find 50mm fans.

Other Thoughts: Do yourself a favor and replace the fans when you build for the first time, they're a pain to replace. Furthermore, mine came with 50mm fans. I don't want to tell you to default to that in case there are multiple models of this case out there but you might want to wait until you open yours up before you order.

5 out of 5 eggsSolid, Economical Case

Pros: Solid design, comes with fans installed, clean design

Cons: None from the mfr.

Other Thoughts: It's a cheap case... It's thinner metal, it's not as polished as the high ends, doesn't have any fancy internal components. When I say cheap -- I mean economical. The case is doing a great job for my firewall. I do not have any abnormal noises from the fans and the build quality is within my expectations from the cost. It arrived without any manufacturer defects. I will buy from this company again.

I could list all of the "cons...." but I paid $50 for the case and was not expecting this to be the build quality of a several hundred dollar case.

4 out of 5 eggs

Pros: Cheep. Works great for me. Works with Norco's RL-26 Rails. Fits My ATX PSU and Mini-ITX motherboard great.

Cons: A couple of the screws were stripped.

Other Thoughts: The 5.25" bays are a little tight but I didn't really have any issues like a lot of other people did. My ICY DOCK ToughArmor MB994SP-4SB-1 fit in them fine.

3 out of 5 eggsHas held up well

Pros: 8 months and this thing is still churning. Its cheap; using it to house a concert/event stage lighting computer which sits in a large and heavy rack (albeit shock mounted) with other equipment that is moved very frequently up and down stairs, lifted and sometimes dropped over small ledges, in and out of trailers, rolled across dirt, snow, grass, bumpy pavement, and grating, once knocked over by a crazed club-goer, and constant time on the road. I'm very surprised that all the fans that come inside are still spinning. Why, with all the moving that happens and road time its had under its belt, I thought for sure the fans would of K.O'd or all the front panel buttons (see cons).

Also, the air flow seems to be sufficient, which is another thing I'm surprised about. The rack this thing sits in gets very hot sometimes.

Cons: After we installed the computer into the case, It didn't turn on. Whenever this happens you immediately think "well, were going to here for a while." Turns out the power button on the front panel was dead, so we wired the power switch to the reset button instead. Minor setback but HUGE time waster (1 1/2 hours) trying to figure out why the computer wouldn't start. VERY aggravated about that.

Other Thoughts: Thank the lord for solid state drives.

4 out of 5 eggsFor the price...

Pros: [-] Least expensive 2U case on NE
[-] Suits my needs: Case #1 pfsense, #2 WMC "server"
[-] Holes line up for rails (for me) whereas my 4224 didn't

Cons: [-] For the price, I honestly cannot think of any perhaps one
[-] Sharp edges, but nothing a file (which is kept handy in my PC building arsenal anymore) won't take care of

Other Thoughts: If you do file the edges in this case. Remove the fans first. Do NOT populate the board at all. File. Take outside and use compressed air inside all around it. Take damp paper towel (DAMP, not dripping) and get what the air may have missed. The last thing you want are metal filings floating/blowing around and wondering why your motherboard fried. (Cleaning the inside of the case is good practice before ANY build anyway!)

2 out of 5 eggsBad product

Pros: Nice looking case
No sharp edges
Good workmanship using quality metal

Cons: -Unit DOA. Will not power up. Reinstalled a couple of times. Motherboard and power supply OK. The computer booted up without any problem when reinstalled back to the original computer case. Probably bad front panel switch.
-Unfinished/unpainted top metal cover. Not good if you want a (finished black paint) look especially in home theater rack application. Server application where looks does not matter will be OK.
-Height of the two 5.25 bay not to spec. Too tight to accept two bay 5.25 removable hard drive canister such as (Thermaltake RC2300101A MAX-2533 Mobile Rack HDD). I had to remove the Thermaltake top cover to make it work. Even without the cover, it is an extremely tight fit!

2 out of 5 eggsgood case, false description

Pros: Solid case, easy to work with, Plenty of room for a 2u short

Cons: 5.25 bays dont hold drives in place and they have no screws holes to screw them into place, I had to leave my cd drive out of the build. Discription states "Comes with full-range power supply" I did not get a power supply, but i made one work from an old build.
