I could be wrong, but I think Win98SE has problems with drives/partitions larger than 127gb. I've never had a need to use larger than a 120gb drive, so I've never investigated this issue. I'm sure somebody will be along shortly to either confirm the 127gb limit, or show you how to safely go beyond it.

Have you considered building a modern-day NAS and putting it on your network? It might be much easier and cheaper to go that route. The added advantage is that you could use SATA drives and also use it for your other PCs and media devices as well.

Personally, I have a 500gb NTFS drive in a USB enclosure that I use to store all my games images, manuals, patches, etc. I just share that out and get the games to my Win98SE box that way. Using Daemon Tools, I just mount the CD/DVD image and I'm good to go.

I too run a Win98SE machine with an AGP 5950 Ultra and a PCI Voodoo 5. Here's how to do it:

Set Up Dual Hardware Profiles

Ok, still does anyone know of a rack mounted or pedestal case that takes IDE or SCSI HDD's? Or a good PCI RAID card for this machine?

Here's some info about the 127GB limit for some Win9x FAT32 systems.

SCSI and IDE/PATA and SATA drives are all the same size: 3.5 inches. Any case with enough available internal 3.5 inch bays should be sufficient. Check here for some options at NewEgg.

If you need more options, you can get 3.5" to 5.25" drive adapters here.

I'm a big fan of the Antec 300 Illusion case. You can fit six drives inside of it. There is also a regular version of the Antec 300, but it's only $10 cheaper and lacks the fans. The Antec 300 Illusion is the better deal. If you watch carefully, it occasionally goes on sale for $45 after rebate.

Also be sure to get an appropriate PSU to power everything.

For a RAID adapter, I used to have a SYBA SD-ATA133R adapter in my system. NewEgg used to sell them, but you can find them on eBay nowadays. I never had any problems with that adapter and would recommend it.
