Hi, thanks for your reply.
I ordered one a few days ago, i could cancel the deal and get a raspberry PI. But i wouldn´t use HDMI too and maybe go for lan and buy a usb to lan device.
I dont have much experience in usb to lan, do you think this works well with Linux ?
Would you recommend canceling the deal and get a PI instead ? So if it got heat issues, why dont remove the whole case and just apply a big heatsink ?
Thank you

Yes, USB Ethernet adaptors are well supported under linux -- there isn't great variety in the chips that are used in these. In my case I got the cheapest one from Amazon, which was in fact a "Wii Lan Adaptor" -- note that they won't necessarily advertise Linux compatibility. USB Wifi adaptors are a bit more tricky, but if you do the research you can find a Linux compatible Wifi adaptor cheaply, e.g. I use a TP-Link TL-WN722N / TL-WN722NC which has a proper antenna + long cable (this one was considerably stronger than a simple usb-dongle without external antenna which I also had, i.e. let me reliably connect to a network which my phone and laptop couldn't connect to).
