I'm not sure on the quality of the philips hdd enclosure (can be seen at EYO for $29.57) but I couldn't find a cheaper 750GB external hdd on staticICE. The hard-drive is the Western Digital WD7500AACS Caviar Green, 16MB Cache.
As a bonus they are also offering around 2 dozen Dual Port eSATA Bracket + eSATA cable (Valued at $12) to early birds.
hey, you didn't post the actual cost (perhaps caught up in the excitement of the moment), lol - DW, i saw that it's $119.85
