i suggest to choose a low profile ram to help to fit better
''the Spec001 can also take a 240mm rad in the front. Again, it's tight, very tight, but it goes in and lines up nicely. In fact with 130mm of space here between the front of the chassis and the anterior edge of the motherboard tray, if you choose carefully a 60mm thick radiator in push pull is entirely on the cards.''
