Which one is the best?

Desktop, HP Compaq 6000 AiO, Pentium Dual-Core E6600@ 3.06GHz

Desktop, HP Compaq 8000, Inter Core 2 Duo E8400 @ 3.00 GHz

Desktop, HP Compaq 8200 AiO, Intel Core i5 2400S @2.50 GHz

Desktop, HP Compaq 8200 and 8100 SFF, Intel Core i5 2400S @2.50 GHz

Laptop, HP 6560 and HP 8460, Intel Core i5 2520M @2.50 GHz

I realize these aren't the best, but my school is selling used computers for $25, so why not.

At a quick glance, I would go for the HP 8460.

if you are using it for gaming at all I'd get the compaq 8200 because with a desktop you can upgrade to a better graphics card. However the laptop appears to have the most processing power, maybe. Laptops are also great for being portable.
