re: large drive. While it may be true that Poser eats HD, its not because of virtual memory; it's about the size of your runtime if you purchase a lot of items. Also, If you are an animator, it consumes a lot of space because of incremental saves of pz3s with dynamic subfiles plus folders of png image sequences. There is an upper limit to the virtual memory swap file of 4096MB or something like that. However, FAST HD is another matter, and it counts big time. I have dual Raptor 35 Gigs giving me 70 Gig in RAID-0 array. This is very fast. From desktop double-click on the Poser6 icon, 8 seconds until completely launched into my default startup. 70 Gig might seem small, but it is just my 'current workspace." I shuttle older projects to a firewire external, and back that up with DVDs, stored offsite. And yes, fans. I have a Zelman cooler on the CPU, two case fans, and individual fans to cool each Raptor. I call this rig "Sikorski". ::::: Opera :::::
