4 out of 5 eggsCorsair 750D Case Full Tower

Pros: -LARGE case. Perfect for just about any gaming setup. I would imagine any graphics card can fit in this case with ease.
-Very novice friendly case. Areas to hide wires, lots of zipties, various screws, grounded screws for your motherboard are already there right out of the box.
-Huge fans included with the case. Fans are very good as well
-Case does not feel fragile but there is a con here(see cons)

Cons: -Fans make quite a bit of noise. Thats what happens when you have 4 big fans in your case preinstalled. If you have the case near your bed...good luck sleeping.
-The front bottom panel is pretty flimsy and poorly designed. It can fall apart, has issues closing, and quite frankly i can see most people just leaving it off(it does expose bottom fans/filter though)

Other Thoughts: Anyone looking for a full tower case should look no further. Unless you can find another full tower highly rated case on a massive scale, this should be y our 1st option. I threw out my old case(midtower) and installed the full tower in probably an hour. If you're familiar with building PCs you should have no trouble.

3 out of 5 eggsNice Case but Arrived Dented on Top

Pros: Working with the case was very easy. It was spacious and well laid out.

Cons: When everything arrived for my new Rampage V build, I was bummed that the top of the case had two significant dents in a very conspicuous location. I was disappointed and still am when I see those.

5 out of 5 eggsPerfect for the H100i

Pros: This case has enough room for almost ANY gaming build! It has plenty of room for my H100i water cooler, which is amazing as well. I REALLY like the fan filters on the top, bottom, and front.. They will become very useful when the dust starts to build up. I will be maxing out the amount of fans this case can hold to make sure everything keeps cool. AND THE HARD DRIVE BAYS ARE REMOVEABLE, THEN YOU CAN PUT FANS THERE!!! ...Fricken awesome. :)
Plus the fans that it comes with look and feel like better quality fans the then usual case fans.

Cons: The case has 4 SSD drive bays in the back of the case, they are great but im a little worried about keeping them cool. They are not in path of any fans. As long as the case keeps cool, i guess they will too. No other real cons that i can think of.

Other Thoughts: I think i will be using this case for more than 15 years. It has the room for any build i do, and it can support triple GPU systems... with EASE.
This is a FULL TOWER case. And its the first full tower i have bought. It is only slightly biggger than my mid tower, and i never plan on moving it. So it is PERFECT. It annoys me when people buy full tower cases and complain about weight and size...
If you are looking for one case to do all your gaming builds for at least 15 years, this is the one. As long as the case holds up to years of play, Corsair will be my new favorite for case manufacturers. :)

5 out of 5 eggsPerfection

Pros: 1. It's big enough to hold my Server motherboard (Supermicro H8DGI-F), that's 12" x 13".

2. It's from Corsair

3. Large side window, simple design and it has a lot of rubber grommets.

Cons: 1. That it can't make me a sandwich.

5 out of 5 eggsCorsair Obsidian 750D

Pros: This case just came in today and it's absolutely beautiful! I love it.

It's huge and there is plenty of room for everything. I'm finally building my dream computer and have been ordering parts over the last couple months but couldn't find the case I wanted to build in. Someone mentioned this one in a review of another case I was looking at so I went to look at this one. That guy was right. This is the case I was looking for.

I was kind of worried about the power supply I bought fitting in It's a thermaltake toughpower 1200 watt gold and it's HUGE! So when I got the tower today that's the first thing I did..try the power supply and it fits perfectly and it sits on the bottom of the case instead of the top. So the fan in it blows the heat out through the bottom of the case through a mesh opening instead of into the computer.

there's room for 3 optical drives which is exactly what I wanted too. also room for 6 hard drives and I think 3 ssd's.

And this is great too: One side has a huge clear window so you can see everything inside. All the wiring is hidden behind a panel with rubber cutouts to pass the wiring through so when you look in it will look nice and clean and the beautiful motherboard I bought (and don't even get me started on the beauty of the video card) is visible.

Building into this case is just going to be a total pleasure.

Cons: It doesn't have legs so I can't walk it around the neighborhood so everyone can see how awesome it is.

5 out of 5 eggsBest case ever.

Pros: Very large and spacious with a ton of options for water cooling. Love the sleek stealth look of the case. The idea of a magnetic filter on top was definitely a bold move by Corsair. 3 spots for 240mm radiators make this case a must have if you want a custom loop.

Cons: None that I can really think of other than the front panel kind of blocks intake air from the fans up front. It's removable though.

Other Thoughts: Top notch full tower case at a great price. If you are looking to water cool your rig, I would highly recommend it.

5 out of 5 eggsWatercooling Friendly :)

Pros: -Watercooling Potential
-Radiator friendly
-Enough room for 56mm radiators
-Huge window
-(Pretty much everything)

Cons: -No bottom dust filter
-Needs bottom radiator bracket to realign the incorrect 120mm (240mm radiator) fan holes

Other Thoughts: I love this case. Upgrade from a C70 Military Green after two months of owning, and that case had issues. I'm glad I made the switch. At the time of purchase, I wasn't planning on watercooling for a few months into owning it, but I'm very glad I decided to get this case. I decided to go into watercooling in October... This case is so watercooling and radiator friendly (besides the bracket that is needed to realign the holes for a 240mm radiator). Inside this case, I have an XSPC RX360, RX240, and an EX240. It also has enough room for my XSPC Photon 170 pump which is huge.

When I purchased the case I wasn't planning on watercooling right away. If I would've know I was watercooling before October, I would've purchased the 900D. Either way, I love this case. I highly recommend it. Keeping it forever :)

4 out of 5 eggsBest case I've dealt with.

Pros: -Large case.
-highly customizable.
-should fit most motherboards and gpu

Cons: The panels aren't as stable as I would expect. Window is fragile.

Other Thoughts: I have two Zotac 970 Amp! Omega gpu's and they fit perfectly with ease into the case. There is more than an inch between the back plate and panel.

5 out of 5 eggsSimple and Beautiful

Pros: The case is Simple and Beautiful with tuns of room. There is also plenty of room for cable management.

Cons: One slight con. The System Panel Connector cables need to be longer by a few inches to allow less strain on the system panel connector pins on the motherboard.

However, I could also say that it's also a con for the MSI X99S SLI PLUS motherboard. If only the System Panel Connector pins were moved to the right by a couple of inches, it would alleviate cable strain and bent pins.

I was able to fix the cable strain/bent pins by connecting M/F breadboard jumper wires to the ends of the cables. The jumper wires added an extra 6" to the System Panel Connector cables.
