I would like to ask a few questions to find out what works best for you. It does not matter if you are familiar with computers or not. The questions I am asking you do not need to be computer savvy. After answering these questions, I'll take care of everything that's best for you afterwards. Ready?
With this question I can get more of an idea of what I can take. Is it more for general use so multimedia, office and internet or even with gaming or even rather in the professional field like 3D rendering, video, photo editing, programming and so on?
What do the individual pieces mean?Wifi:This allows you to connect your computer to the Internet without a LAN cable.Bluetooth:If you want to connect a controller, speaker, smartphone or anything else without cable, you need Bluetooth.CD/DVD or Blu-ray:Nowadays you do not have to have that, movies and music can be watched online. Games and programs can be downloaded from the Internet.SD Card Reader:As the name implies, this is if you often work with SD cards of photo-/videocamera and want to connect the SD card directly to the computer.LED lighting:You can have lights on your computer so that you can see something inside, that is just to make it look beautiful.Microsoft Office:Microsoft Office is unfortunately not for free. Word, Exel and PowerPoint are Microsoft programs that arround 120 € (Check price).Informations:More than 6 USB ports are available, HDMI (and DisplayPort) as well as LAN input and the sound card are already preinstalled.
This way I can see what to take without exceeding your budget. Small hint, building, installation and help is free, as it's written everywhere.
