Hmm... Pop an other PCI HD controller card in there and slap in a couple of those 250 GB drives for backup space... maybe on RAID, then use one of the faster sets of HD's for the games.
2 motherborads a go (before I rmaed for cheaper options) my motherboard came with 4 SATA Channels, 4 IDE 100 and 4 IDE 133, as well as 2 floppy drive channels. (that is 4 sata ports on board, 2 ide 100 ports on board, ad 2 ide 133 ports on board.)
Of course... power consumption may be higher that way, so I opted for a cheaper more power efficient board for a while... and now I have:
DFI Lan Party NFII Ultra B
Got it for the hardware specs, not the name or the glow in the dark bullcrap or the overclocking options (limited.)
-4 sata channels
-2 ide 133 channels
-2 ide 100 channels
-2 floppy drive channels.
-gigabit lan port
-10/100 lan port
-400 FSB support
-3200 ram support @ dual channel
etc...
Not bad, but still not PCI-Express... which I sort of regret!
