Recently got an old Dell Dimension 4100 that I am going to hopefully use to run Windows 98 for retro gaming. I got it in unknown condition with no HDD. It powers on, but DVD drive is stuck shut. It wants to open, but can't quite do it. Using the paper clip method will push the gear back, but nothing else happens. Need to see if any other thoughts before I basically have to take both sides off and the front panel, (top latch not budging and hate to break it), to completely remove drive and take it apart. Also on a side note the tan plastic HDD caddy, metal HDD retaining bar, and tan colored back panel screw are missing and likely thrown out somewhere along the line , (what a shame☹☹☹). Anyone know where I can find any parts? Looked on eBay and only systems for sale...☹. Thanks for any help.
