The lid or case cover has a moulding in front of the HDs that looks as if one can cut it out, maybe that would help airflow - maybe a fan mounted on the outside here sucking (I don't care what it looks like)?. . . >> See: http://www.xlr8yourmac.com/guest_rev1/ For mounting a fan in front of the HD. Scroll down to the last paragraph "Optional Fan Mounting." Also see http://www.geocities.com/glenstrek/7500_fan.html for detailed directions of mounting a fan on the metal grill behind the drive. If you check the comments link there is an explanation of how the air flow in these machines work. (I have photos this type of installation I can send you off list) If your drive is 1/2 height (approx. 1 5/8 inch thick) cooling could be an issue in the 7300's bottom bay. I have read posts describing overheating disasters and other posts from listers who had no problems at all. If in doubt you can buy an analogue indoor/outdoor thermometer and tape the outdoor sensor the drive and monitor its temp. That's what I do. My 7500 has an 18 GB 1/3 height 7200 Western Digital in the lower bay. It can reach 115 F when room temp gets up into 85-90 F range. And I'm using a grill mounted fan. --glen PS. In answer to your external drive query, the difference in speed between Bus 0 and Bus 1 is a theoretical 5MB/sec so you will probably not notice a big difference in performance. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
