Ok. thanks everyone for your help so far. Now i am looking for a desktop that i will use with dual screens (if it makes a difference ) mainly info stored on the cloud(not local memory ) and mostly work online. What specs should be relevant to me?
If you are going to use Wi-Fi make sure that it has a built in Wi-Fi card with at least 802.11 n, if you are going to use LAN (plug a wire in) good for you, it's faster.
The size of the enclosure. You will find full size towers, mini, micro and slimline, choose the one that is best for you. If you have space, the bigger the better, you will have more airflow and upgrading components in the future will be a lot easier.
HDD vs SDD. If you are looking for a computer that you will have most of your storage online, you do not need more then 250GB. That said, a SSD will give you an incomparable difference in start up speed.
Graphics. If you plan on having a dual monitor setup, you are going to need a graphics card with 2 outputs. Most modern desktop will come with 1 VGA port and 1 HDMI. Just take note of what you have before you go monitor shopping. It would be a shame to find a good deal, and then you realize you have to go find a new video card.
Software. Some computers now will ship with Microsoft Office, and it will come out cheaper then buying it separately. Never spend more because they offer you an Antivirus software! You don't need it, windows defender is by far efficient.
