     Total agreement on that point.

     SSD of adequate size is beyond my means.  So was finding out that
the HP Pavilion was not repairable.  But the terabyte hard disk
was <$70 and the new case price as noted.
     But I got the drives swapped around and my new external Comkia
USB3.0 case works with it.  These cases are really inexpensive now
with the design refined & the Central Computer shop has them at
 >$20.  Much simpler to install than my old now likely broken NextStar
and lighter as well.

     I gave up on copying TAILS but there is a new version available.
The complex .sig files and the lack of easily accessible checksums
seem to defeat the security if I am downloading and copying
the files.  I will get it if someone wants TAILS but they will
have to do the checksums and signature authentications.

     Well I am still setting up the Dell and later today will swap in the
old drive from my HP Pavilion and install the later version of PCLinuxOS64
on it, if everything goes well.

     Now fixed as reported earlier.

     I just tried out Fedora 27 Workstation and I do not much care for it.
If someone wants to seen my simple evaluation of the product send
me a note and I will mail it to you.
