As someone who initially wanted to switch to an itx build but saw the expenses, this was the best alternative. Almost no compromise when it comes to component fit. A 160mm cooler is just enough clearance if you're not using aio.
The psu bracket is movable so you having a 3 slot gpu is viable.

I'd HIGHLY recommend getting this case of you're wanting to go smaller workout breaking the bank with itx.
Just be aware that if you buy this case, having a side intake will mess with thermal performance. Rather stick to a top intake and rear exhaust.
