5 out of 5 eggsGreat Full Tower

This review is from: Cooler Master HAF X - High Air Flow Full Tower Computer Case with Windowed Side Panel and USB 3.0 Ports

Pros: I bought mine 8 months ago at a different store, as an "open box" item. It was perfect right out of the box. I had no problems with installation what so ever. The cable management is very good. I would buy another one of these if I need too.

Cons: Not really a con so much but the two "hot swap" bays in the front, are really not hot swappable. I am replacing these two ports with a different cage. I also had some problems with cover on the power supply. Just a hunk of plastic that doesn't fit very well.

Other Thoughts: Recommend Red iStarUSA 2x5.25in to 3x3.5in SAS / SATA Trayless Hot-Swap Cage, Model: BPN-DE230SS-RED.

I put a 4 port in the top 3 ports and not only does it work great, but it is also very stylish too.

It goes very well with the red and black theme of the overall box.

4 out of 5 eggsexcellent case plenty of storage

This review is from: Cooler Master HAF X - High Air Flow Full Tower Computer Case with Windowed Side Panel and USB 3.0 Ports

Pros: you will never have to worry about anything not fitting in this beast of a case...it even comes with wheels if you want to go that route.

Cons: one of the fans was bad on my case :(..I plan on calling coolermaster and having them send me a new fan asap..not to big of an issue i guess .. these things can happen

Other Thoughts: I would definitely say this case is worth the money. full tower plenty of cooling..room for anything you want..and a lot of little things such as wheels,video card support holder, and all that..

4 out of 5 eggsNice quality case with lots of internal space

This review is from: Cooler Master HAF X - High Air Flow Full Tower Computer Case with Windowed Side Panel and USB 3.0 Ports

Pros: Solid build.
Plenty of space for easy cable management

Cons: Machining was slightly off on one of the four side panels thumb screw holes. Have to really push on case and side panel to get screw hole to align with panel to put thumb screw in. Over all a minor issue, but would have given rating of 5 except for this.

Other Thoughts: Would definitely recommend. Had no problem putting a Sapphire Nitro R9 390 into this case!

5 out of 5 eggsThe King of High Air Flow

This review is from: Cooler Master HAF X - High Air Flow Full Tower Computer Case with Windowed Side Panel and USB 3.0 Ports

Pros: You can't beat the extreme airflow of this case. This case takes 4 200mm+ fans which is pretty remarkable. I think it is the only case to do so. Plenty of room for most hardware you can throw at it. It supports almost every non-proprietary motherboard size. It also has a 140mm fan slot in the back. It even has an included bracket for a 120x38mm fan meant to cool your video card if you want to use it.

The 2 x 200mm on top & the 1 x 140mm in the back is meant for exhausting and the 1 x 230mm front & 1 200mm side fan are meant for intake. The best airflow I've seen in any case.

It has the holes for AIO Water Coolers. I use the Corsair H100i and it works perfectly and you only need the 2x120mm fans since the 2x200m fans are on top. I'm not sure if the 280mm AIO water coolers will work since I've never used one of those.

It has a lot of good wire management especially in the back.

Cons: I had to hammer a few areas in the back since it was not straight and the pins to close the case were very tight.

The add-on fan adapter is a little flimsy so be careful when screwing it onto the hard cage (if used).

I don't like the PSU cover it only works if you have a normal length PSU. I think if you have on of those really long PSUs like the eVGA 1000+ watt it won't fit.

Their 2 included 5.25">3.5" hot swap brackets are wasteful since it would have been better to include a 2x5.25">3x3.5" module. Plus it has no fans in the back so unless you have a green drive it will overheat.

The included fans are pedestrian. Cooler Master fans in general don't have a lot of airflow.

Other Thoughts: This is probably the best case for high airflow especially if you have a lot of high end hardware.

I actually bought this to use as a SAS expander with 13 WD 6 Tb Re/Se drives with the Supermicro CTJBOD1 power board. So I actually have a ton of heat coming from the 13 Enterprise drives and even at full load the drives never get past 34-35C which is a lot better than my old HAF XM.

I recommend to replace all the fans with higher airflow versions:
-140mm fan use the Fractal Design Venturi
-200mm fan use the BitFenix Spectre Pro
-230mm fan use the BitFenix Spectre Pro

3 out of 5 eggsI really respect Cooler Master, but I think I may have received a bad apple case.

This review is from: Cooler Master HAF X - High Air Flow Full Tower Computer Case with Windowed Side Panel and USB 3.0 Ports

Pros: Strong, tons of space. Easy installation. I really like how the front bays works.

Cons: Many of my screw holes were unaligned. The paint comes off very easy. I could scratch it off with my fingernail. The filters were hitting my fans and had to cut the filters a little so they would not make noise.

Other Thoughts: Obviously I knew this before I bought it, but I really wish the Cooler Master icon on the front was in a different place, it annoys me a little. I wish that the front ports had a slider just like the power and reset buttons.
