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.

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

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

Pros: sleek look,
3 temp sensors and separate temp display so you dont have to use software.
2 front usb 3.0
decent amount of areas to hold cables.
build material is not at all flimsy,
for a $66 dollar case would most definitely buy again
screwless pci clips so you dont have to screw in the pci cards.

Cons: first and formost
nothing larger than 10" video card with nothing in adjacent 5.25 bay however if you drop to a lower pci-e slot on ur mother board u could fit a 11" but BARELY
not really a con but i dont see why theres 3.5" bays, i think case would have been better if the 3.5 was removed along with 1 5.25 bay and add one more 120mm fan spot in the front.
on that note, only 4 fans not to mention the front fan is "blocked" by the cover when closed although apon closer look a normal fan wont supper any with cover in closed spot

Other Thoughts: bought for a blue black theme compter
fx-8350 pro
asus gtx 960
16g ram
1 128g ssd
1 1tb hdd
xspc custom water cooling processor cooler.
650w psu

5 out of 5 eggsExcellent Quality Budget Case

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

Pros: - Slick, solid design. The chassis is made of steel, so it feels very sturdy.
- Comes with 3 fans in total. Two with blue LED's and a rear exhaust that doesn't have LED's. There's also room for one additional 120mm fan on the top if you'd like to add one.
- Cable management was relatively painless. Much less room, though, and it would have been a bit of a pain.
- Temperature sensors and the display on the front are a nice feature.
- The clear portion on the side is fantastic. It has kind of gray tint to it, but just enough so you can still see the goodies and lights on the inside.
- Plenty of expansion bays.
- The front door seems to be pretty sturdy. It's magnetic, which is nice.
-

Cons: - Front-facing USB ports are 2.0, not 3.0. Kind of a bummer, but not a deal-breaker for me. I have a few 3.0 ports on the back.
- Be careful which video card you try to put in this case. I'm using the Sapphire Radeon R9 270X 2GB and there's not much room to spare between the end of the card and drive bays.
- The SSD mounting spot was a bit awkward for me. I was able to get my SSD mounted securely with two screws, but it would have been nice to have pre-cut holes for a 2.5." Not worth dinging an egg for, but worth calling out.

Other Thoughts: I got this case in a combo deal and I love it. In my opinion, it's a steal for the price. It looks nice, but it's not overdone. Also, there's plenty of room for upgrades.

3 out of 5 eggsOne Awesome Case - One Horrible Flaw.

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.
It has lots of nice features; easy to mount HDD, temps readout, nice solid door, nice looks and the list goes on!

Everything worked and still works perfectly fine after a year.

I've had this case in my main build for a while. Watercooling is somewhat easy (too and rear-mounts. It goes hand-in-hand with the NZXT hue and Source.

The case is relatively silent with an h100i inside of it. Stock fans are surprisingly really good!

I thought the door would be a fingerprint magnet due to it's high gloss finish, but it's surprisingly not !

Cons: -Bad cable management (why the 2eggs off)
-No USB 3.0

It's especially important to have a clean looking case when you have such a eye catching windowed side panel..
The cable management will be horrible for you of you don't have a modular poker supply.
Even with a fully modular power supply I had a hard time working things out.. but I always found a way to make it work.



One of the expansion slots retainers broke the first time I removed it! Fortunately I have GPUs installed so it's all good.z

The door became a but noisy but I'm sure I could just oil it down and it'll be fine !

Other Thoughts: It's overall great. You get what you pay for in the construction though. It feels sturdy
It would've been nice to see USB 3.0!

Great mounting solutions and if it wasn't for the cable management, this would be one of the nicest case out there.
