Armored Core: Nexus. Best Farming Method?
I finished discs A and B of Nexus, and I wanted to buy everything before moving on to Nine Breaker or Last Raven, what's the best farming spot?

i have a huge full-tower case (Cooler Master Trooper) that has been going for 15 years now, and i'm getting real tired of it from having to break my back to plug a usb cable, and it cramping up my small desk.
so i have been thinking of upgrading to sff case for a while now, and initially i wanted a console style case like the Silverstone FTZ01-E or the RVZ03, but later checked the Fractal Design Era 2 and liked the way it looked, so i'm at a loss. I've never considered shoebox-style cases because i don't like the way they look, but now I'm thinking they may have advantages over the Sandwich or Console cases.
Note: I have a 180hz, 1440p monitor, and in order to make the most of it i need an RX 9070XT-level gpu which is beefy.
I also don't like the idea of consooming every 5 or so years, so the build must last for 10-15 years, which only one gpu upgrade in this span.
EDIT
considering the proposed placement of the case on top of the black desk on the right and pushed to the corner of the wall (extension cord moved under desk), the dimensions of the case should not exceed the below constraints:
Base Length: <=35cm to allow about 8cm of space from the back
Base Width: <=20cm to allow ~13cm space between the case and the wall
Height: no restriction.
case front (not side) will be facing me.
preferred airflow: inlet from the front/bottom; exhaust from the top.
EDIT2
after checking out some of the suggestions in this thread, i've narrowed down the required capacity to 18-23 Liters (nothing smaller, nothing larger)
