I am attempting to refurbish an old dell dimension 5150 desktop computer from an even older dell xps r450 being used for parts. A minimum of $$ expenditure is part of my plan, basically a 'learning' experience. I have an hp pavilion desktop as #1 and an Asus Eee PC netbook as #2, so I can afford to experiment with my dimension 5150. So far, I have installed the internal floppy drive in the 5150 frame and have that working, although it looks kinda weird from the front. Now I wish to install the xps hd as an ide drive in line with the optical drive preinstalled in the 5150. I will deal with the master/slave setup later. Presently I need to determine a way to secure the ide hd in the 5 1/4" drive bay (below the optical drive)in the 5150 frame. I believe I require an adapter kit for a 3.5" to 5 1/4" installation. However, the mounting screws are rather ambiguous to me. The 5150 5 1/4" drive bay does not appear to support installation of a second ide drive without a specific cage for the hd. Before I commit any further $$, I would appreciate any input from you experts as to my quandry. Grats in advance,eh.
