there is no 3080 that can fit in the ghost S1 except for the founders edition.. even the slimmest evga RTX3080 XC3 will be blocked by a notch on the ghost S1's panel.

And since the founders is a blow through design, the ghost S1's sandwich layout will choke the 2nd fan and you're giving the card a death sentence.



Im personally using the sans warhead. It's a small factory so expect the build quality to be utter crap and most of the screw holes doesnt fit properly... and a very flimsy mobo mount which i epoxy glued brass pieces to enforce the rigidity. All things aside, i'd say this is the hands down the most optimized layout for super small ITX cases.

there are 2 versions the 2 slot version will fit the evga 3080 XC3 no problem...if you use the 3slot version, the ventus 3X and palit 3080 game pro should fit. but because of the low cpu fan clearance with the 3slot model, you will be limited to using the NL9 which is not sufficient for anything higher than a ryzen 3600 unless you can find a way to force fit in a 120mm AIO. (where the tubing will be in the way of the gpu) 

Also do note that at the moment there is no safe SFX PSU to run the 3080...Corsair's SF750 will be running close to 80% load so It's not recommended.  Im waiting for the coolermaster 850w gold SFX to launch and see the reviews before deciding on the upgrade.
my plan was to get the asus tuf where i will saw off the tuf logo notch and shove the pcie power pin directly into the gpu without the connector housing to solve the clearance issue. Will definitely post pictures of it, meanwhile this is how it looks like currently

Maybe try custom watercooling 
Since card length wise shouldn’t be an issue, just that you need a matching top hat for the S1 clone too.

But disclaimer first, if 240mm radiator cannot cool the cpu + 3080 effectively, don't quote me on it  That 3080 will definitely heat up the cpu too.

My humble sugggestion if you dont want much headaches: NR200... it’s only very very slightly bigger than the Ncase.
For me, i just enjoy the challenge of making a powderful PC that fits in a bagpack so im going ahead haha

I believe the 3080 cards that are out right now wont fit that clone.
Most named clones like Aklla and Kevcase are based on the design of the MK2, and I havent seen anyone put a 3080 inside it yet except for the FE.

The EVGA GeForce RTX 3080 XC3 BLACK GAMING definitely fits an MK3, and you can buy the case from Taobao.
I am not sure if there will be local distributors for EVGA for the 30 series as there was for the 20 series.
