By SATA computer i guess you mean you use SATA drive's and opticals for it?, in that case, most (depending on when your motherboard was made) should have at least 1 IDE port on the board, my motherboard is about 2 years old, i bought it 1 year ago, and it has 2 IDE plugs, not that i use them, but since you have 3 drives you wish to use, possible you could buy a RAID PCI card and run them through that, like this card http://www.ebay.com.au/itm/Ultra-A [...] 3469wt_907
