Great Full Tower Case 8/3/2020 7:42:10 PM

Pros: - Lots of room to work
- Plenty of space for even the largest CPU coolers and video cards
- Good wire management
- Unbeatable Corsair Support

Cons: - Case material could be a little sturdier

Overall Review: I've had this case for about 7 months since the build and it was a pleasure to work with. Good layout, wire management, and quick attachment options. Exceptional airflow especially when using 140mm fans set in proper push/pull configuration. Plenty of loops for cable ties. Has the window so you can show off your stuff. A really great option for anyone who has the space and wants exceptional airflow for air-cooled setups. Works equally well with the largest of radiators if liquid cooling is your goal - you can run a lot of plumbing.

I am an experienced builder. I have used various Corsair products for a couple of decades. What continues to sell me is the value for your money and the integrity that this brand has. I had an amazing experience with Corsair customer support related to this case. About one month after completing the build, I inadvertently struck the front panel when moving it to a different location, causing a big unsightly dent and scratch on it. Working at home full time due to COVID, I lasted about a month before I couldn't stand looking at it anymore. I contacted Corsair to find out how I could obtain a replacement front panel, and asked for pricing and ordering information. Tristan Gonzales, my support rep, sent me a replacement for free. Zip. Nada. Zilch. I reiterated that the damage was my fault and I was merely contacting support to find out how to order one... and he would have no part of it. The replacement part shipped internationally from the Netherlands to Florida, USA, via DHL. I had it within a few days of shipping. No doubt that wasn't free. Absolutely amazing in today's world that any brand will incur that expense to ensure their customers are satisfied. The replacement panel I received was flawless and a perfect drop-in fit. Tristan actually kept the case open until I confirmed with him that it was the correct part after I received it. One of the most incredible and painless customer service experiences I have had of any brand in recent memory that went way beyond my expectations. I've never had an issue with any Corsair product I have ever purchased, but this experience has sealed the deal and will keep me coming back for a couple more decades for sure.

Awesome Case 8/3/2020 1:21:29 PM

Pros: -Lot's of room for big liquid CPU coolers along with plenty of room for different power supply units and video cards.
-Simple design, not over flashy and quality is good.
-Has 3 bays for CD drives or other front expansion media drives.
-Airflow seems decent and the fans included are very quiet.
-There are plenty of hard drive bays which can be moved if needed for extra space or fan configurations on the bottom or front.

Cons: My only issue so far with this case is occasionally the front USB header will give me an issue only on the far right USB slot. This is the USB 2.0 plug, on rare occasions when I plug something into it it won't be recognized. If I slightly wiggle the plug a tiny bit it will be fine. (Probably a lose contact or something inside the plug).

If you go with a 3 fan liquid cooler you probably won't be able to utilize the top CD drive bay as it will take up that space. With my 280mm. twin fan cooler my DVD drive fits fine in the top bay.

Overall Review: I like this case a lot. It was easy to install hardware into it and has plenty of space to fit all your big coolers and other hardware. It has a simple elegant design that I like since I don't do much with all the fancy LED lights. (This case doesn't include any for those wondering). The overall quality seems good and it has some weight to it. It feels good to handle when working with it.

For those wondering, my "current" setup is...

ASUS AMD AM4 ROG Strix X570-E Gaming ATX Motherboard
AMD Ryzen 3950X CPU
Arctic Cooling Liquid Freezer II - 280 (AIO)
Gigabyte Graphics Card GV-N75TWF2OC-4GI (Soon to be swapped to something better)
Some old 650 watt PSU from 2010.. (Also soon to be swapped)

Great case, well priced too 7/29/2020 7:05:01 PM

Pros: - Lots of space inside
- Three coolers included
- Super quiet
- All of the parts are super easy to reach inside this tower
- 4 USB ports, very convenient
- Allows up to 3 CD/DVD drives
- Looks really good
- Reasonable price

Cons: - A little bit bulky

Overall Review: I bought this one to build my very first PC. Assembling was very easy because this case is SUPER spacious, but on the other hand it is really big and bulky. It seems like I could build another PC right inside this case without even removing my current parts :)
I would recommend to consider choosing something else unless you're okay with this huge beast sitting on your table or next to it (which applies in my case))

Corsair Obsidian PC Case 7/28/2020 12:44:15 PM

Pros: Full tower. Makes the install so much easier. Had a mid tower which was fine. If you have the room, can't go wrong with this case. Would buy again.

Cons: Had to buy more fans, but that was my choice.

Overall Review: Recommended and would buy it again. Newegg shipped fast and the price was very good.

Good quality case 7/18/2020 12:44:40 PM

Pros: Lots of space in this puppy.
Good quality.

Cons: No cons really I can think about.

Overall Review: Great, good quality case. Top filter and front filter can be easily taken off and cleaned. I bought this case because I wanted to match the same brand Hydro Series H115i top fans CPU water cooler and Corsair HX Power Supply. Both are compatible with the Case. The Case has been working without a hitch for over six month now.

All good but one thing 7/12/2020 8:52:32 PM

Pros: If you want space to work with and room to show off your beautiful components this case is the way to go.

Cons: The power on/off button comes with white LED's, mine in this particular case (no pun intended) has a problem, the left side lights normal and good, the right side lights on and off randomly all the time which kind of kills the aesthethic of such a nice case, i already have checked that everything is connected good and wheres supposed to be.

Overall Review: The case may be what you want or not, in my case (hehe) im pleased with The Corsair 750D it fitted my needs althought a little dissapointed with the Front Panel LED problem.

It's Heavy.....NOT a quality case. 6/30/2020 3:40:04 PM

Pros: Looks beautiful

Cons: Quality control must have taken the day off. The middle standoff had a piece sticking out of it. Almost ruined the motherboard. Power supply setup is weird. The way hard drives and SSDs attach is weird.
Only 2 fans came with it. No HDD LED. The manual is a joke, they might have not put one it it would have been better. I hate pictograms.

Overall Review: It's a beautiful case. Very heavy when the Plexiglass sides are put on.

Manufacturer Response:
Hello Daniel,

The middle screw wouldn't be a standoff per se, it'd be to place the motherboard correctly into the case. How is the power supply setup weird? How is the way the HDDs and SSDs attach weird? 2 fans did indeed come with it, and there's also no HDD LED. Are there any issues we can help with regarding the case with its intended features? If so, feel free to contact us:
