There are a coupel of alternates to Bright 
OpenHPC - which works great, but you have to do a bit of self learning. CentOS/Redhat/SuSE though

Qlustar - Debina/Ubuntu/CentOS
I am less familiar with Qlustar.
My advice - give some serious thought to Bright and Qlustar. Try an installation of both and see which suits you the best.
Remember that Easy 8 and Qlustar are community supported - but you are ready for that.
