Hi all, my first post (and third try..). I'm planning to build my custom plexi-alu case and, in search for silence, i ordered a zalman cnps6500 al-cu(which i mount horizontally) ,a quiet gpu(hercules-ati-9500 with noisless fan),and a quiet psu. The main source of noise now is my old hard disk maxtor 740dx (7200rpm) with his 30-33 dB . My idea is to build an alu enclodure filled with acoustic foam. The problem is that the disk will produce a lot of heat and so i decided to place a large heatsink (wich will extrude from the enclosure) on top of the HD, hoping to mantain temp acceptable. A sensor will be included to monitor the temp. This is the rough idea: and this is the internal view: I was wandering if any of you have ever done something similar. Do you think it will work? Thanks for any comment.
