Much as I like Win98SE, it doesn't handle over 512mb RAM, and isn't real poser friendly. Grab a copy of Win2k Professional, or if you absolutely MUST have the latest crap and integrated DRM, WinXP pro. Please note that the only thing you can't do on Win2k that you can do on XP is use an Intel Hyperthreading processor to it's fullest potential. 1 gig+ RAM. No less. For drives, I suggest getting 2; put win2k and it's swap on one, install all your poser stuff and nothing else on the second; this allows you to make backups easier, and even add some portability to your poser files. a 10gb or better drive would be fine for the poser drive. even better, get 3 10gb drives, and make them into a RAID5 rig, you'll never lose anything to a crash (and have about 20gb of space to play with). Um, I haven't hear or seen anything that says your video card matters any, but i suppose P6 COULD make use of the GPU in some way and they just aren't advertising it? regardless, it doesn't matter in p4 or p5. BTW, I'm a MCSE. Speaking as a Microsoft Certified Systems Engineer, XP Sucks.
