Cheaper ?
           How to not go broke, fixing or buying old relic PC's           

Answer, buy something better even used PC from 2007 are vastly better than older, ones. Do not buy  or use or throw money at years 1999 to 2003 PC's with the China bad CAP.'s disease.

Why spend hard earned cash on dead PC's, when the sea is full of live fish, in fact PCs in the USA are in GLUT status now. (too many fish, the law of supply and demand is in your favor)
The best deal of new Notebooks  is a Chromebook for $119 at Walmart and sold in  vast other stores. (so cheap it is throw away when it breaks, as it surely will)

Walmart refurb Monitors, cheap,  $35 to $60 or even less some days.
Avoid all monitors older than 2010 made they use short lived CCLF back lamp tubes. If the manual for the Monitor shows, no mention of LED , avoid it, if the manuals mention "Toxic, Hg or Mercury" avoid it  (means CCLF)
In the year 2010 the wide screens were changed to LED backlamps first, then the narrow screens later (hint hint)
Avoid all things with the 4:5 ratio square like screens !
My HP avoidance list is here.

Cheaper good PC's:
Walmart,  PC refurbs , near new for $77 or less some days, there are great deals on used Refurbs and even a waranty, (shocking) 2007 and newer is my rule. My rule is, it must run Windows 10 64bit or I walk on by.
EBAY also lists greast HP refurbs , look there too.!

GOODWILL® stores,  Laptops.(2007 or newer is best 2010 even better !) avoid all older Laptops !

GOODWILL® stores,  PC's

I walk in to GW  store and , read the Microsoft sticker  COA tag W7  , and walk out for low cash. (near free compared to any new PC or new MOBO) (Best is HP that shows full support on the HP web site!.)

Buy a great used  HP work-station XW4600 or newer, like this?

Any Xw-nnnn ,  up are great desktops,  the best IMO.
Any Z400 up is even  better with Zeon processors. ! Really the Z600 is a jewel.!

I like HP , they are the best, for hardware and the best documentation of any makers,  some makers have ZERO DOC's other than color, plug in guides,  mostly useless, IMO.
Read the Xw4600 page. SEE?

These are my Idea's on how to not RUN XP ever again, and not go broke.   (I see a guy buy a Laptop for $1000 bucks and think, gee, I could buy 3 laptops with 5 desktops for that cash?)
If all you need is one home PC, get the ATX full sized desktop above and a chromebook for travel.
