There are three versions of the Optiplex GX270 desktop, if you have the Small Mini Tower, you can use any IDE DVD/RW drive similar to the drives shown HERE
thanks for your help
i have a model like this : http://cgi.ebay.com/Dell-Optiplex-GX270-2-8-Ghz-512MB-40GB-Hard-Disk-Drive-/260610837931?cmd=ViewItem&pt=Desktop_PCs&hash=item3cad9dcdab
so i really don't know which dvd-rw will be appropriate...
maybe this: http://cgi.ebay.com/NEW-DVDRW-BURNER-DRIVE-DELL-OPTIPLEX-GX240-GX260-GX270-/370375384895?cmd=ViewItem&pt=PCC_Drives_Storage_Internal&hash=item563c17df3f#shId
only i have to spend : US $59.95 (+ US $35.95 for the shipping)
It seems that i must buy a drive like this:
Can a buy a drive from another brand (in order to save some money) which will be compatible with my pc?
