One addition, no matter what, if the OS is MS Windows based, make sure it is a 64 bit OS, so you can actually install and make use of the 8~16 GB of memory you may install. The 32 bit OS severely limits the RAM allowed, no matter if the hardware allows it to be installed.

And remember (Win 7 or higher), you will qualify for a FREE Win 10 upgrade when released to the public. So time those purchases well and snatch up a ton of Win 7 & 8.1 units right around release time on e-bay or elsewhere. I'm buying Win 7 Premium (64 bit), multi-core i7 laptops now, restoring & refurbishing, upgrading them, and selling them often right now. The drives are large, cores are fast, they take 8~16 GB RAM (and that promised FREE OS Upgrade is a great selling point). But, I add my special touches and tools.

Sadly nobody is building a decent add in MMX graphics card anymore...An old HP ZD8000 (17" LCD 1 HD Bay), or DV7 (DV7 has a large 21" LCD and 2 HD bays), was the perfect unit w/ the add in cards (used a ton for Karoke units because of the extreme graphics reached, needed, and used, and each takes 8 GB RAM), but they run really hot until tricked out w/ copper shims on the graphics chips internally, and a copper bridge added to the 3 fan cooled triple vented copper heatsink from them to actually connect to that heatsink. (Then they run nice and cool w/ super ATI graphics). Those laptops weigh a ton though due to the 3 fans internally. Case is very heavy. (NOTE: Stay w/ the ATI graphics and less fear of the dreaded black screen & necessary non-leaded solder needing a reball of the vid chip problems & issues).

Anyone have a super water cooled Desktop or Server unit running CAD? How about liquid nitrogen cooled yet?

I build em' & sell em', but I can't donate them. SRY. (But I am reasonable).
