My price range is £500 to £1,000. Need PC to do mostly for surfing the net. Also for folding @ home project so dual or quad core cpu would be better. Not much gaming, but decent graphics card for picture editing etc. Decent size HDD/s & possibly RAID 0 or 1? Would prefer Blu-Ray drive & DVD-RW?
Novatech are indeed a good option along with several other. You might want to put some thought into the spec computer you want though. The uses you've listed could result in a number of completely different computer specs.
