Seasonic SYNCRO DGC-750, 750W 80+ Gold Power Supply, CONNECT Module Cable Management, SSR-750FA2, Must be Used with Case Q704 to Function Normally.

Pros: 1. Reverse-ATX Design:
The motherboard mounts in the case upside down (CPU at the bottom, PCIe slots at the top).
The motherboard mounts on the left (not the right) side of the case. The Tempered Glass Side Panel is on the right (not the left) side of the case. Seasonic offers custom PSUs for the case with a unique Power Distribution / Cable Management Cover (a.k.a. CONNECT Module Cable Management).

2. Very sturdy, thick metal, no exposed sharp edges. The Tempered Glass Side Panel has a steel frame, and full length Aluminum Handle that matches the Aluminum Front Panel on the front of the case.
The Power and Reset buttons are solid. The Power LED is a White Line on the side of the Power button (towards the front of the case). See Cons #4. Dust covers for the top audio jacks and USB ports. See Cons #5.

3. Four included 120 mm fans. Three in the front (intake), and one in the rear (exhaust) of the case. See Cons #3.

4. Lots of Magnets, holding the Tempered Glass Side Panel closed, also holding the Dust Filters, Cable Management Cover, etc.

5. Well packaged in a sturdy oversized box. The case is suspended on both ends by thick foam. The case itself comes in a black fabric bag. Both sides of my box were damaged in shipping (by large punctures). Fortunately the case itself was not damaged.

6. Accessories come in their own cardboard box and includes: the users manual, a plastic "toolbox" of screws, a pair of fabric gloves, a soft cloth, and Velcro cable ties.

7. 10 YEAR WORRY-FREE WARRANTY on the PSU, 2 YEAR WORRY-FREE WARRANTY on the case.

Cons: 1. Expensive, unless you can find a Combo deal (i.e. Case plus PSU).
Proprietary PSU.

2. Very Heavy (over 33 pounds with power supply).
The Tempered Glass Side Panel alone weighs about five pounds. The PSU is over five pounds (depending on the cables used).
The glass door is easy to remove, just swing it open by the aluminum "handle", and slide it upward off the two hinges. However, the glass door needs to be open almost 90 degrees to remove and replace (i.e. you need a lot of room).

3. The three front 120 mm fans come pre-plugged into a 1-3 PWM Fan Splitter Cable. The cable on the single rear 120 mm fan is very short.
All four included case fans have "odd" four pin connectors. The polarity tabs are longer than normal.
I was unable to connect the four included case fans directly to the PSU CONNECT Module Cable Management fan ports.
I had no issue connecting the 1-3 PWM Fan Splitter Cable to the PSU CONNECT Module Cable Management fan ports.
I had no issue connecting other three and four pin fans I own to the PSU CONNECT Module Cable Management fan ports.
I had no issue connecting the four included case fans directly to my motherboard fan ports.

4. No HDD LED (which I miss). Stupid in my opinion. If you don't want an HDD LED, just don't plug its two wires into the motherboard.

5. The Audio and USB ports are on the top of the case, just waiting to be filled with dust (once the covers are removed). The USB-C cable is too close to the CONNECT Module Cable Management and does not lay flat as you close the Metal Side Panel.

6. The four thumb screws holding the Metal Side Panel and Power Supply Bracket to the case seem kind of cheap, and easy to strip the threads. I believe they are actually designed to remain attached to the Metal Side Panel and Power Supply Bracket when they is removed from the case.

Overall Review: 1. This first thing you need to do is remove the metal retaining bracket that holds the glass door closed.
There a two tiny Philips screws, on the bottom of the case, holding the metal retaining bracket in place.
I put the two screws back in their holes to prevent from losing them. I put the metal bracket in the accessories box to keep from losing it.

2. The PSU is smaller than a normal ATX PSU. It only generates 12 Volts.
The CONNECT Module Cable Management converts 12 Volts into 3.3 and 5 Volts.
The PSU attaches to a bracket (with four standard PSU screws). The bracket then connects to the case with two thumb screws.
The CONNECT Module Cable Management attaches to the (outside) left side of the case with five small screws.

3. The PSU will not Power On unless all three cable bundle connectors are plugged into the CONNECT Module Cable Management. Its easy to dislodge the smallest connector (the one with no retaining clip); the PSU will NOT even Power On unless it is fully inserted.

4. No place to mount an Optical (CD/DVD) drive, but they are pretty much obsolete now.

Conclusion: If you like the look and size, and don't mind the weight or expense, you will probably love it. It's a matter of taste. It wasn't really my thing, but it grows on you.

Pros: - Has integrated fan and RGB hub.

Cons: Comes with short power cables to the motherboard and GPU. It comes with two pairs of PCIe cables. Both pairs are not long. But the shorter cables are 'really' short and are not long enough for my 2-fan GPU. If you have two GPUs to install, maybe you will need to have your own extension cable.

Overall Review: Works well till I try to install my 2nd GPU.
Includes fan and RGB light hub is a plus when you have more fans than the sockets on your motherboard.
