what exactly is the difference between 80 and 68 pin SCSI drives? im going to be buying 3 37GB 15K seagates for RAID 5 and not sure which to get.

80 pin drives are commonly "hot swap"...go in special hot swap removable drive bays.

what kind of host adapter will be going in the rig? unless you have a special need for 80 pin hardware (like a specialized server case with hot swap bays as YeOlde mentioned), i would just make life easier by going with the pin count your controller has. no need for a pin adapter.

I couldnt find out the pin count of my controller. I looked all over and couldnt find it. It's a Adaptec 2010S ZCR, going to be conntected to a Intel SE7501BR2 server board.

2010S?... i think that's a zero-channel RAID adapter, so the RAID adapter itself has no ribbon connector. it plugs into a PCI slot (64bit/66MHz) and acts as an extention of the mainboard's integrated SCSI, so you will use the SCSI ribbon connectors off the mainboard still. just be careful which PCI slot you plug it into. some boards have PCI slots that run at different bit width/frequency and sometimes a different voltage. just check with the manual for the mainboard to be sure which PCI slot is which.

Ya, if I remember correctly it goes in slot 4. I never found out how many pins the mobo connectors had. Maybe I need to dig a little deeper.
