that's what I read about air flow 2. 5 is a better choice ,, world of sat would of fitted a 500 gig for £40 when I ordered my box so this must be available on there web site for that amount or should be less if I've got to fit it ,, and by rights it should fit strait in with the screws and grommets they supplied ,, but I can't seem to find it on there site but I'm sure it was a 500 GB sata drive
