Agreed if I was going atx. I would try and see if I could get a custom L1.0 with a reverse motherboard tray like the R1.0 has probably would lose small bit of rad space but would look nice.
Can't wait for my R1.0 720 Total Rad space is nothing to sneeze at either. Parvum don't certainly consider proper rad space.
Does make me laugh when in win say they have excellent rad space and you can fit just one 360MM rad in a atx case. Sorry but not sure how that is excellent when a little air 540 has 480 total.
