4 out of 5 eggsGreat case for the price point!

- Convenient HDD storage
- Case is solid, doesn't feel weak
- Great price for the look and features

- Thermal sensors aren't very accurate (but still useful, see other thoughts)
- Airflow is minimal compared to better cases

4 out of 5 eggsNot for High End. Mid Level Case. No LED Fans.

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

Pros: This case looks great, but do your research before you purchase (see my cons section). First of all my case did not come with any Blue LED Fans. How is this even possible? When I've ordered these in the past they came with at least one front LED case fan so I'm not sure.

After buying this case many times I can say that the following is not accurate.
120mm Fans
1 x 120 mm Blue LED Front Fan
1 x 120 mm Blue LED Side Fan
1 x 120 mm Blue Fan

Cons: 1. Does not always come with LED case fans
2. Does not fit most large cards like the 280X without modification.
3. Sub par air flow because of all the drive bays.

If your case comes without a front LED fan and you want one, the only way to install one is to remove the 3.5 external drive bay inside your computer by removing the rivets and unscrewing the lowest internal drive bay.

If you want a gaming PC that uses this case and is modified to fit the 280X or 290 and bigger visit fxware's website to build a custom pc with this case.

4 out of 5 eggsGreat case for low price

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

Pros: Case looks good and the led lights are not to intense... just a nice soft glow. The case has good air flow and the fans included with the case are pretty quite. All the components mounting location were correct and the manufacturing is above average. Steel on the case is a nice thickness so it helps with the sturdiness of the build. The built in temp gauges for the CPU, HDD, and the System are nice if you like to know those things. Overall its a good case and I am happy with most of it, a few things that I would change but good overall.

Cons: I hate to say anything bad about this case because everything else is nicely done but...
The cable management on this case is non-existent and if you load it up with drives you will end up with a tangle of wire. You will be supplied with 2 zip tie mounts that you may mount to the side of the case to secure the wires but the mounts are only strong enough to hold the wire out of the way... not from managing cables. The front panel connects are poorly marked, after some careful examination of the wires from the front face i found a small arrow on the connect, which i assumed indicate was the power wire.

Other Thoughts: As stated the case is a great case, if you can get pass the wire mess that you end up with because there is no good way to route the cables. I will hold everything that an average builder could want, I will state that If you plan to run liquid cooling... this is not the case for you.

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.
