A few weeks ago I was finally able to borrow a gfx-card from a friend of mine, and thus I was able to test the Efika. Got Debian Linux installed on it and everything seems to be working fine. Now I just need to save up some money for an own gfx-card and things like a new PSU and a new harddrive, as my economic situation has been pretty bad lately. But hopefully things are looking better in the future :)
