If I had to choose a motherboard, cpu, ram, psu and hard-drive just for reliability - and nothing else - for use as the main pc for my company, what would you suggest? No overclocking will be done (There's no need.) And no dedicated graphics necessary either. Would you suggest RAID 1 (I was of the opinion 3 years ago but the seller of the accounting software was against it and he won that round). Also, he managed to persuade the others that 2GB of DDR2 was OK, as was a 32 bit system. I'm suspecting he hadn't been that knowledgeable on 64 bit systems then. Hopefully he is now. We've been working with some prebuilt pc since then. It's got an Asus board, some low-end PSU, and a Q9400. It was fine, till it started messing up... Badly.
