The above MSI RTX 4090 Suprim Liquid X unboxing video will give you a good overview of what you get with the card. Besides the card itself, MSI includes a silver-white Suprim mouse pad, and that's about it.
The card and radiator together weigh 2336g, or 2395g if you include the 'quadropus' 8-pin to 16-pin adapter. But if you look just at the graphics card (minus the radiator) it's only around 1350g (+/-50g from the tubing). That's a lot less potential weight on the IO bracket and PCIe slot, and of course the card only occupies two slots instead of the 3+ slots we're seeing on most other 4090 models.
The card dimensions are 280 x 139 x 42mm, while the radiator measures 275 x 117 x 54mm. The tubing between the card and radiator is about 44cm (17 inches) long, which should give you plenty of options for how to install the radiator in a larger case, but might get in the way for smaller Micro ATX builds.
With the 240mm radiator, there are obviously dual 120mm fans helping to keep the card cool. The fans are 26mm thick and use standard 4-pin connectors, so if you wanted to replace them with something else — or add two more fans in a push-pull configuration — you can certainly do so. (Extra fans would need power from somewhere else most likely, unless you want to add your own splitters.)
Besides the radiator fans, there's also a custom 95mm fan on the card, near the back and located over the VRMs and power circuitry. It's not clear how much this fan contributes to cooling, as the main plate for the AIO cooling covers the GDDR6X memory and GPU, but it should move enough air to ensure the VRMs don't overheat. One thing it won't do much if at all is push air out the IO exhaust vents. The waterblock and pump will block most of the airflow in that direction.
Otherwise, the MSI card takes a pretty traditional approach. There are three DisplayPort 1.4a outputs and a single HDMI 2.1 port, just like most other RTX 4090 cards. Power comes via a 16-pin 12VHPWR connector, and the card includes the aforementioned quadropus adapter that we've seen with every 4090 card.
There's a modest amount of RGB lighting as well, naturally. On the "front" of the card (with the fan, which will normally face downward in most cases), there's a chevron near the end of the card that lights up. On the top of the card, the "Suprim" logo also lights up — and pulses by default. Finally, on the card backplate is a diamond-shaped cutout that lights up. It looks as though there are metal 'stickers' on top of a larger LED panel, but only the uncovered lines visibly light up.
All things considered, it's a nice looking card, with a brushed aluminum shroud and backplate that conveys the premium aesthetic, assuming you go in for the water-cooled look.
