4 out of 5 eggsGreat case but a bit loud

Pros: - Love the color scheme
- Roomy
- Easy to replace drives

Cons: - Sounds like a Jet Engine that is about to take off once I turn on a gfx intensive game. and I mean within seconds of me turning it on

Other Thoughts: Unsure if the jet engine is fully the fault of the case, but when I disconnected the side fan the noise level went down noticeably. Unfortunately then my cpu temp started climbing like crazy (to 65 degree C in about 10 minutes). Will replace the cpu fan for a quieter one and get back on this info

4 out of 5 eggsNZXT Guardian 921

Pros: The case quality is good for the most part. I personally am not impressed with any of the built in temp sensors in cases. These are just surface sensors that you tape to something you want to see the temperature from. I would rather use the on board sensors for this. My daughter did like the sensors and the way the case looks. We improved on the red color buy adding additional crystal fans with red LEDs that gave the case a much better glow.

Cons: None really

Other Thoughts: Make sure you look at all the pictures and understand the color is not as bright as some of the pictures show.

4 out of 5 eggsNZXT Guardian Red

Pros: -Very nice looking and well lit
-Able to lock side panel
-LED Temp sensors on front.
-Front door panel looks clean and hides drives.

Cons: -front speaker port only plays out of left speaker
-LED in 'Y' on front went out only after a couple months (and i dont see where to order a replacement LED)
-Kinda tight fit after you start adding PCI cards. (cable management is pretty bad)
-Wouldn't mind a Kingston lock slot

Other Thoughts: While i was able to fir the Cooler Master v8 gts in the case, the side fan stopped it from being able to close. solution found in Prolimatech's 15mm slim fan. (no LEDs but i have LED strips to compensate.)

4 out of 5 eggsGreat for the Cash; Looks like a Cylon

Pros: -Looks like a Cylon!
-Decent sensors, not overly tight for low-rise cards
-Add another 120mm fan on top with a red LED and it looks even more boss

Cons: -Uh, how many 5.25" bays do you think we need?
-Seriously only 3 bays for HDDs? Huh?
-Ratio of 5.25" to 3.5" is inverted, obviously
-Large profile cards make cable routing a nightmare

Other Thoughts: honestly for $70 and if you are clever with cable routing regardless of card choice, buy it.
Plus, if you're a BSG fan, you'll earn cred...so say we all.
