is 8gb single-board computer enough to compile firefox, inkscape, libreoffice, etc.. on linux

* right now, i found only raspberry pi,
but they were released almost
three years ago,[ 1 ] good user
support and works out of the box

* web search has found results for
using packages & user support

* my questions:
* are there other vendors offering
similar products?
* should i wait another year or any
product might be available with more
than 8gb?
* should i consider only ram?

* why sbc?
* to compile my most used packages
for every release of gcc version including
minor dot updates
* after an year, conpile my own linux
kernel
