The Fractal Design R4 is another good choice, it's more oriented towards silence than the Arc series.
You can grab a Corsair Obsidian 550D (I think it's a better option than a 650D) or 350D (microatx) if you're willing to swap fans but they're pricier. The 550D doesn't have a window however.
Otherwise, you can grab a corsair Carbide 330R if you can find it for $70. It's like a 300R with a higher top (so that you can fit a H100i). The issue is the rear fan is 120mm, so 140mm tower coolers will be a tight squeeze. I measure my 300R that this is based off of to have 171mm CPU clearance even if they claim 160mm. Also, the top isn't filtered and the side and bottom don't have fan mounts.
nevermind about the 330R, it has no window
The NZXT H630 has no window either.
I believe the Thermaltake Urban S31 has terrible airflow judging by reviews ; the S41 is pricey for what it has.
Are you just looking for a Silverstone
FT02 alternative on the cheap?
@ Bit_reaper he probably needs good airflow for GPUs, the H100i is a CPU cooler. Unless the case comes with a bottom fan mount or fan mounts in the side panel/side window then it's unlikely to be good cooling for GPUs.
