7384.0. "Open DECPC450ST" by 33102::JAUNG () Sun Mar 16 1997 20:26

    We are using a DECPC450ST which is a mini-tower model.  We are trying
    to open it to replace the disk.  While facing in front of this PC,
    we can only remove the left-hand side panel (or cover) with lots of
    sweats.  The rest of the cover (top and right-hand side) looks like 
    one big piece and we have no clue on how to remove it.  Any suggestion
    or pointer will be highly apprciated.
    
    Thanks in advance.

That's it. Only the left panel comes off (and then some metal shielding).

The 450ST uses rails so to install a disk you don't need access to other side.
It isn't easy, but then very few PCs offer good access.

I have mine fully loaded internally: two Disks, a tape and a CD-ROM, all SCSI 
drives, so connecting them is very tight.

    -.1 Well..., yes..., but you might have mentioned that to get to the
    disks you have to pull out the release mechanism next to the front
    bezel, so you can remove the bezel to extract the drives.
    
    1	Remove the side panel
    2	look to the right side (front panel side)
    3	you will see a metal tab located just about where the sheet metal
        separates the M/B from the Drive Bays
    4	pull that tab out (to the left of the system when facing the front 
    	panel)
    5	then lift the bezel up and away from the bottom slowly until you
    	can unhook the bezel from the top of the case. 
    	(the front bezel I'm refering to, is the one around the drive bays)
    6	to replace: hook the top of the bezel into the case and slowly
    	force the bezel over the drives ( a tight fit!)
    
    **	The drives are on rails that click in..., be prepared to use a
    	screwdriver or some other flat device to help push the rail clips
    	inward to loosen them up for removal.
    
    Ah..., the Jensen Box, contrary to the going opinion, probably the best
    Mini-tower ever built.  Built like a tank, took a licken' and always
    kept on ticken'!

    Thanks for input.  We'll do it very very carefully following your
    instructions.
