Server Score & UPS/APC

Server RAM is different from normal RAM (from what I have read).
In server RAM they include a extra 'bit', its either 0 or 1.
For every byte, its either a odd or even value & the RAM gives a even value a '0' & a odd value a '1'.
If once the bytes travelled further & the computer detects a odd value byte, but with a '0'. ( or even value with a '1' )There's something wrong.
So it knows to go back thru & reprocess that byte.
OK, its only going to get 1/2 of the mistakes, but that helps the computer a fair bit.

And, I'm not that knowledgeable about computers so this explanation is as best I can do & also my interpretation..

And, check what the CPU & power supply's are worth on eBay etc.
I checked model numbers of a tape reader server & they wanted like $800 for the power supply's.
OK, its defiantly not worth $800...& it might have been sitting there for 18 months for sale.
But, if somebody suddenly needs one 'Right Now'.
$800 (+ p&p) is the least of their worry's...
