FYI. Like Emeraldsky says, these are excellent deals. It seems that Fry's/Outpost is helping a lot of the drive manufacturers (at least Seagate. Maxtor, and Western Digital) blow out quickly obsolescing PATA inventory.
A bought a few 160, 180, and 200 gb drives in the last few months--all rebates came in, but they're just slow as all rebates are. I am still waiting on three rebates from from Fry's post-Thanksgiving sale though. (200gb WDs at $49 after rebate.)
In any case, these drives are great for your new MSI K8N-NEO4 Platinum/SLI rig!
