Lot of three 3.5" To 5.25" drive bay brackets, to install 3.5" drives into vintage PC/XT/AT era computer cases. These brackets are 3 sided, heavy and look like brass (though they are steel, a magnet sticks to them.) I took these out of some old computers way back in the day before scrapping them, I believe two were from Gateways, with 286 and 386 processors but I can't be sure. The third one with low profile front is marked as being made for Toshiba on the bottom.These might fit modern PC case with 5.25" drive bays, but are really best for vintage computers of the PC/XT/AT era (especially if you want to use authentic period correct parts.) I believe 2 of these are intended for 3.5" hard drives, and one is for floppy/zip/tape drives (since it has a lower profile front. There are screw holes on the inside to line up with 3.5" drives, and screw holes on the outside to mount in cases (that match 5 1/4" drive screw holes.)Two of the drives (with full front) are about 6 1/2" long and about 5 11/16" wide and 1 1/8" tall. The one with the low profile front is 6 5/8" long, 5 9/16" wide and 1" tall on the sides.
Please be sure these will fit/work with your vintage computer case(s)! No returns for incompatibility, please ask questions before buying!
