The IBM models with glass platters were the 75GXP, 40GV, 60GXP, and 120GXP.
The specified weight for Barracuda IV/V/7200.7 is 544g for 1-platter and 635g for 2-platter.
And now for something completely non-HDD-related: I find that if you run 2 identical fans in parallel (airflow-wise) at the same (nominal) speed, there is a large increase in tonal noise caused by the blades, compared to having 1 of those same fans (in this case NMB 3110SB-04W-B40-E00) at the same speed in the same setup. 1 fan or 2, the exhaust air from my system (besides that from the PSU fan) isn't perceptibly warm. Even with the highly restrictive fan grilles in this AOpen case.
I'm starting to suspect Intel overstated the required case airflow in a piss-poor attempt to make up for the inadequate stock cooler supplied with the high-end Pentium 4 models (by high-end I don't mean high performance, just the top of the Pentium 4 range).
