3 out of 5 eggsDissapointed

This review is from: NZXT Guardian 921 RB 921RB-001-BL Black SECC Steel, ABS Plastic ATX Mid Tower Computer Case

Pros: - Looks cool if you are into LED's and transformers.

- Screw less drive bays make for an easy and hassle free install.

Cons: - GPU bracket screwless bracket was difficult to take off

- Sever lack of cable management options, I have to squeeze on the side panel and stuff some of my loose psu cables in the HDD brackets. No ties or grommets. In this price bracket I would have expected better.

- Case is a bit crammed, though being a mid tower this is expected.

Other Thoughts: I haven't yet tested the temps but the airflow seems pretty good.

4 out of 5 eggsNZXT Guardian 921 RB

This review is from: NZXT Guardian 921 RB 921RB-001-BL Black SECC Steel, ABS Plastic ATX Mid Tower Computer Case

Pros: Solid case, doesn't feel cheap
3 built in fans that ventilate well
built in temperature sensors
easy to remove panels

Cons: LED's aren't very bright
front panel fan has a lot blocking the air it pushes out
doesn't fit some video cards (my XFX GPU was too big)

Other Thoughts: Not sure if this is a common issue, but the cords hooked up to the ports on the front of the case were set up incorrectly. the cord that was supposed to be between the USB's there and the motherboard was actually hooked up to the headphone and mic input on the front, and vice versa. A weird manufacturing issue I guess.

3 out of 5 eggsGood starter case, if cable management isn't a priority

This review is from: NZXT Guardian 921 RB 921RB-001-BL Black SECC Steel, ABS Plastic ATX Mid Tower Computer Case

Pros: The Guardian is a pretty good case. Unfortunately, it has a fair share of flaws. However, it does have some very good points to it.
-Simple to build
-Useful and accurate temperature monitors*
-Decently efficient cooling design

The case is well built and keeps my stuff quite cool despite the use of a stock AMD fan and very poor cable management. It's very much impressed me in that regard.

Cons: *Those temperature monitors work; kind of. Within minutes of receiving the case and turning it on, the monitor readout on the front panel burned out, nearly causing a fire. The panel was replaced by NZXT at no charge, but they sent the wrong color; I have a red front, blue rear.

The case has very, very little room for cable management. I actually had to press down hard on the panel to get it to close. A fully modular PSU might alleviate the issue.

The front panel is very flimsy and weak feeling. The case also has a fitting issue with DVD drives and card readers.

Other Thoughts: I, sadly, don't think I could recommend this case to anyone. The tiny, tiny space given for cable routing is almost unforgivably small. This needs to be expanded before I could consider a recommendation.

4 out of 5 eggsSturdy, crowded.

This review is from: NZXT Guardian 921 RB 921RB-001-BL Black SECC Steel, ABS Plastic ATX Mid Tower Computer Case

Pros: All steel, 3 fans, room for one more.
CPU, HDD, and SYS temp probes for front panel LCD
All cables well labeled.
Appropriately gamey-blingy with blue LEDs.

Cons: Drive bay enclosure prevents some video cards from fitting.
Side panel fan takes a fair amount of space.

Other Thoughts: Very sturdy case, and nice looking. Everything went together more or less OK, EXCEPT... the video card (AMD Radeon R9 R290X) would not fit. There is a lip on the bottom of the upper drive bay enclosure that prevents the card from fitting. Bending it straight down 90 degrees with pliers and a hammer solved this issue and didn't obstruct anything else so I'm not sure why it's there.

The side-panel intake fan is pretty thick and uses quite a bit of space inside the case so make sure your cables are out of the way before you try to put it back on.

Otherwise, this is a good case and with a modular power supply to eliminate excess cabling the fan issue won't be a big deal.

4 out of 5 eggs

This review is from: NZXT Guardian 921 RB 921RB-001-BL Black SECC Steel, ABS Plastic ATX Mid Tower Computer Case

Pros: -Very nice looking
- Provides decent cooling
- Big enough to fit most graphics cards without modifying anything
- Comes with temp probes which is nice a little feature
- Has room for cable management, but not much
- It's very lightweight
- Love the window and color scheme
- The fans that came with it are, in my opinion, very good especially for being stock. Never been dissatisfied with NZXT fans

Cons: - Some of the pins inside of the molex connectors broke when I plugged them in. So I was unable to use the front temp screen.
- Seemed kind of cheap in construction, however it wasn't very expensive.
- There is not very much room for cable routing in the back. Especially if you do not have a modular power supply.

Other Thoughts: My brother wanted this case for his build that he was putting together. He really loved the look and design which was one of the bigger buying points. That, and it was easily affordable by him. The biggest con that I have with this case was the lack of routing space behind the motherboard tray. It doesn't help that the power supply I gave him wasn't modular and was just a cable disaster, but we made it work. He really loves the temperature probes, even though they don't work now because of the broken molex connector. And not to be toooo nitpicky, but the glossy front will smudge easily however, it isn't much of a concern to him.

4 out of 5 eggsAwesome case

This review is from: NZXT Guardian 921 RB 921RB-001-BL Black SECC Steel, ABS Plastic ATX Mid Tower Computer Case

Pros: It is a really good looking case with a slick style. Is easy to work in and has descent cable management.

Cons: I took off an egg because of two thing, one it doesn't have any USB 3.0 ports and second it should have a bit more room in the back for cable management I barely got all the cables in there

3 out of 5 eggsDecent Case

This review is from: NZXT Guardian 921 RB 921RB-001-BL Black SECC Steel, ABS Plastic ATX Mid Tower Computer Case

Pros: First of all, I would like to start by saying I really think this is a nice case. It's flashy, aesthetically pleasing, and overall I am pleased with it.

It would be a nice case for the average PC builder.

Cons: The only few bad sides to this case are as follows. It's much too small to be used by anyone other than average computer parts. I should have researched the size a little more and i would have known my Corsair H110 would not fit inside of it. To be honest, I don't think any of the other Corsair models would have fit in this case to be honest. So if you get this case, I recommend getting an air cooler. I also do not like the fact that all of the drive bay stuff is riveted so you cannot remove them. I would have a lot more space to put other stuff if I could remove the big bulky drive bay stuff that is in my way.

Other Thoughts: Overall a decent case, but if you are serious about building a nice PC with larger pieces and/or you need a lot of space. This case is not for you. I personally will be buying a larger case, but its too expensive to return this one--so for now it's being used as a nightstand.

Manufacturer Response:

Hello, Valued NZXT Customer

We appreciate the feedback on our case the Guardian 921 RB which is meant to be a simplistic budget build case. It is in fact true that the NZXT Guardian is not a friendly water cooling case, that being a budge build case. They relied on the fact that the user was going to use a push and pull system for the case, not buying an expensive All in one or custom loop set up. If at all any parts do become faulty please visit us at support.nzxt.com and submit a request at the top right. In turn we would be able to send out those parts. If you have any further questions or concerns please feel free to contact us at +1-800-228-9395.

Kind regards,
NZXT Support.

2 out of 5 eggsShould have known better

This review is from: NZXT Guardian 921 RB 921RB-001-BL Black SECC Steel, ABS Plastic ATX Mid Tower Computer Case

Pros: lot of room

Cons: when you buy refurbished especially a computer case, you figure they have fixed it..well no eggs for me, came broken with front bezel pin broke, it is now resting in a pool of expoxy..been building computers for over 15 years and have watched case quality nose dive to pitiful. should have stayed with tried and true antec 900. this case is cheap plastic .
Will be buying an antec

Other Thoughts: i have always gone by the axiom, with electronics, you get what you pay for it is still true stay away from a refurbished case..shame on me thankfully it was only 60 bucks
