@DJ_Bucho I have. Very easy once you remove the panels. You just have to be a bit delicate because the screws go into the aluminium.
I put an AMD 9600X3D on an ASUS X870I gaming and a Noctua low profile cooler.
I had an old AMD 580 GPU I chucked in as I’m running proxmox on it so no need for high end GPU although my RTX 5080 SFF would have fit.
Thermals are ok, not good but not bad. Although you can fit a standard 120x25mm fan at the bottom I used a Noctua 120x15mm as the cables from the PSU would have interfered.
