IDE is not an option if you want 1-3 TB of hot data. With two devices per ide channel you would need a lot of ide controllers. Get a real disk controller that has two or four channels supports 64-bit 66mhz PCI or even 100/133mhz PCI-X and supports 15-30 drives per channel. A redundant controller that would be good too. This may mean duplexed or two controllers to the same disk storage system.
Get an external disk hotswap storage system and SCA 80-pin drives. Don't waste your time with less than 10k, I would go with 15k rpm drives with a budget like yours. Lots of memory, lots of controller memory with a battery backup and a highly cached filesystem like xfs. I hear XFS is really good for big maildirs.
