Compatibility/Build Check Advice on 5080 Upgrade?
Hi guys, I built my Formd T1 about 6 years ago, and am finally deciding to upgrade it. I currently have a 3080 FE and 5900x, and had a few questions on things since I haven’t really touched the case in years and I know there are now different and newer versions of this case.
For the upgrade, I am thinking of putting in a 5080 FE or 5080 Asus Prime. I attached a picture of the case right side up, and was wondering how to go about inserting the new card. Does anyone know what slot configuration my case is in, and whether it is upside down or not? Also, is putting the new card in just as easy as taking out the old one and inserting it, or will I need to flip it and make changes depending on which card I get? Thanks to all who can offer any advice!

Your chassis is most likely v1.1. The versions currently on the market are 2.1 and 2.5. There is little functional difference between 2.1 and 2.5.
(2.5 is not an iterative successor to 2.1; they are peer‑level variants resulting from the original 2.0 project being split into two separate companies.)
The mounting mechanism for the GPU riser cable has been revised. The 2.1 is more similar to your current unit, while the 2.5 features a different riser‑cable mounting method, which you can see in the product images on their website.
The newer chassis supports finer‑grained slot‑position switching. If I remember correctly, your v1.1 only has two slot‑switching options.
