NEVER EVER EVER consider buying an Asus S-Presso barebones PC.
Within 6 months the HDD was cooked due to in-adequate cooling. I then leant the PC to a friend who had blown his CPU, and he told me last week it wasn't booting. I bought it home and checked the HDD out on my other PC, which was fine. I then plugged it in to boot and a got the magic smoke. One of the transistors on the mobo has fried so it's going in the trash!
I will of course strip it down, but the CPU may be dead too.
