Was Cosmos S, now Lian Li PC-A77B or V-2010?
I like the layout of the Lian Li much better, especially for wc’ing. It’s very similar to the (much cheaper) Rocketfish. The Cosmos has always felt oddly cramped to me. However, if you don’t like having to mod your case much, the Cosmos is probably the better choice. The design of the top allows you to mount a triple rad fairly easily. A front mount may be possible with both cases, but the Lian Li will require cutting to mount the rad anywhere else. You MAY be able to get away without cutting on the Cosmos.
