Yeah, I'm using Rosewill Magnetar ATX cases. Which are extremely friendly to build in... but they have ZERO top venting. No mesh, no 120/140mm fan mounts, no AIO cooler mounts, NO HOLES NOTHING (but solid metal).
Was thinking of getting a friend with sheet-metal experience to cut a blow-hole. Just like the custom PCs in the 90s/2000s.
Or I could just get a few more Rosewill Stryker M cases, those have 240/280mm mounts on top, with magnetic dust filter.
I used one of those to build my R7 2700 rig, put the 240mm CoolerMaster MasterLiquid Lite 240 on top there. Was a really tight squeeze with my Asus ROG STRIX B450-F ATX board, I could only put in a few mobo mounting screws, because it was a mm or two off in clearance, and wouldn't fit quite square.
(*I dislike jerry-rigging a build, but this was a personal build, so I said "screw it" and went with it. Not something that I'm proud of, though, but given the components, I really should have dremeled into the "pre-fab ATX I/O shield bracket cover".)
