I unboxed the item yesterday. I did not get keyboard,mouse,or wireless antenna. I had a keyboard mouse combo around and a wireless antenna. I tried booting system. It got past post and onto lenovo splash screen and bam it went into a boot loop. The os had not been installed fully. I contacted the company. I am waiting to hear back from them.I can fix the issue myself but paid for a fully functioning system.To think it would save money to buy a prebuilt system enstead of building myself SMH.
