Lenovo S500

Fast, quiet, virtually no bloatware - only came with McCrappie AV. Lots of punch for an SFF computer. Overall the customer I bought this for couldn't be happier

No cons that I could see.

Upgrade to win 10 took too long and qas painful to do as i had to wait for it to be sent to me and then turned out ti be a reinstall from scratch and i lost everything

it's small form

it's a nightmare to change from Windows 7 to Windows 10 not at all user friendly

It is neat and fits easily on the desk. It seems to work quickly, but I have upgraded from an old (2007) computer so may be easily impressed.

Lack of a written manual.
