I would like to replace the DVD drive of a Compaq Presario R3000 with a 9.5mm 2nd PATA/IDE to SATA HDD Hard Drive Caddy Tray Bay (please, see it at http://www.newegg.com/Product/Product.aspx?Item=9SIA4E01FK6529&nm_mc=KNC-GoogleMKP&cm_mmc=KNC-GoogleMKP-_-pla-_-All+Desktop+Hard+Drives-_-9SIA4E01FK6529&ef_id=U1CTggAAAYTnIRJ8:20140418033651:s), install an SSD drive in the drive caddy tray bay and make eventually that SSD drive the primary drive. Is that possible using the product I gave you the link for? I couldn't find who manufactures this drive caddy tray bay and therefore I was unable to find out if it's compatible with Presario R3000.
