I thank those for the welcome.  I can agree about more damage coming from overchilled HDDs, but on my present system, I need to keep a 24" boxer fan blowing into the case to maintain drive temps under 50C.  When I keep the air moving, they stay consistent at around 32-24 C.
As for knowledge...well, if ya wanna know why they ran Binary Coded Decimal-based machines for banking, I can tell ya about that.  (It was to avoid that extra fraction of a cent in interest created with floating point math that some programmers routed into their own accounts.)  
I can also tell about the first multi-processor mini-computer (Burroughs B-900...that's who I worked for) which was a great machine...unfortunately those who marketed it didn't know nuttin about computers so I'd have to go in after the installation and make it work right.
Ohh...I started out with a TI-99 toy, then went to a Commodore 64 and then a 128.  I considered an Amiga, but went with MS-DOS based machines because there was more of a market for what I wsa doing on the side...writing dBase III applications.  I've worked on a vast array of Burroughs systems, from mechanical adding machines to B-7900 and A-9 mainframes, HP3000s, IBM AS400s and a whole buncha server boxes.  When I retired I specialized in writing interfaces between machines that didn't speak the same language...like the AS400s.  It was a lotta fun to get data out of an Oracle database and into the 400s flat file system although they called it "an  object-oriented system.  You can call files anything ya want, but if they're just a collection of pre-defined records especially without inheritance, they're flat files.  
Yeah...it's been an interesting journey.  Most of the time I use the machines for photo editing and other graphic development and from April through October I'm at hot rod cruises, sports car and bike races or on the salt flats.  I have a 29 Model A rat rod (what else would a rat have?) and a car that my partner and I are hoping to have ready for the salt this September.  
I play blues bass and Hammond organ (I'm much better on bass than organ...but I'm still workin on it) and I'm a widower living alone in a big house that I bought for my wife before I lost her.  Things is what they is.  Can't change what already is.  Oh...I've been a friend of Bill W since 1992.  
My main sites are

http://www.raytherat.com/Welcome.html  I maintain a whole buncha other ones.  I thought retirement would mean takin it easy, but I've never worked harder nor enjoyed it as much.  I'm livin a dream.  Best life I've ever had.
Edit: I've ordered a full version of Win 7 Pro.  I figured that since it was gonna live on an SSD, I didn't want to fight the upgrade process and scatter the SSD's data. Easier to do it once and not mess with it.
