Thanks for the kind words. It's not that great of an engineering feat, but the card fits nicely. Mostly I wanted to inform people this card can fit with the backplate on, with a slight modification.
I understand the holding-off approach. Tbh, I think the 3090 is too expensive of a card, but I wanted an upgrade to my monitor and its refresh rate for so long. Coming from my still very capable 1080TI, I was also waiting for the 3080TI, but since the announcement that the 3080TI was delayed due to current stock-conditions, I decided to look for a regular 3080. For several days I was unable to track down an EVGA 3080 xc3, but in my search I stumbled upon this 3090 in stock at some store. Bit the bullet on the purchase and the card arrived the next day. Felt a bit dirty, knowing people have been waiting for months on their card, but hey, that's why I purchase only after a stock-check.
I don't know what case you have in mind, but for the dan case at least, and even aside from the current stock shortages, the choice in 3080-GPU's is very, very, very limited. This post by Dan gives you an idea what cards fit: https://smallformfactor.net/forum/threads/dan-a4-sfx.252/page-176#post-218290
For now, I didn't find the time yet for really long gaming sessions, but I did play an fps-game for about an hour on my old monitor. 2560x1600@60Hz, high gfx-settings (not ultra), framerate around 60fps, so not stressing the card too much. GFX/CPU/mobo stayed within max temperature-thresholds. I didn't write down the exact temps. Only my m2 drive gets way too hot sometimes (>115°C) and throttles. I tend to think that was already an issue before, since this was the first time I checked the m2 temps. I'll be trying to fix that with an extra 40mm fan.
Anyway, I have not really stress-tested this setup yet, because my 600W PSU is barely sufficient. Quality high wattage SFX PSU's currently also suffer from severe stock shortages, but I did manage to find an SF750 in stock this week, so ordered it. If all goes according to plan, I will fit that PSU and the 40mm-cooler in my dan case puzzlebox by the end of the week. Will try to stress-test it a bit afterwards and assess thermals and throttling. I'll post the temps from the hw-sensors afterwards.
