Sorry dude or dudette. You seem to be the one getting overly defensive about your opinions on these matters.
You asked someone to point out why your horribly written OP was horribly written. Then attacked the person who nicely points out where you broke down into non-sensical rambles and even gave you idea's on how to structure it.
You asked someone to point out how you overplaid. Then attacked the guy who shows you how you can get new, unused, not 4 year old hardware, for cheaper.
What you purchased was a well built workstation at a cost where most manufacturers would skimp. That thing is built like a tank. But parts wise, knowing the general failure rates of most equipment. The amount of different pieces that could go bad. The cost of replacement parts (as you noted the cost for a NIB being LF being $230, the out of ATX spec mobo, the out of ATX spec PSU, the cost of finding a replacement case if that gets damaged), and the likelihood of an issue make paying even performance competitive prices for the hardware not worth it.
But again you were looking at but even then I would almost rather get an OEM system at $400-500 then to be relying on the unknown variables like how and what the system had been used for the last 4 years and how much wear is on those parts internally.
I am known (also paid for) for my acuity in discerning what is THERE. (Along with my Salsa chops and otha stuff.:biggrin
Trust me, this puppy is as healthy as the day it was born: 3/24/11. (Not 4 years old.) Same deal with my two older Optis! I even feel guilty when I get lust for more speed, given the health of my last one.
I also downloaded Dell diagnostics ISO, burned it to a CD, booted the puppy with it and then ran the very, very long test not the short test.
Confirmed what I already got re the health of the system. The unknown, with focus and delving work....become KNOWN.
That the big Opti cases get uglier and uglier.....is moot. Saw a comment online about this. I liked it.
Can't waste more time in this convoluted, useless stuff....with blindly, narrowly invested humans with their windows crazy glued/epoxied, soldered shut.
Have fun, guys....it was interesting for as long as it was.
Be happy.
