I've a second hand NAS200 here. But I do have little (let's say big) problem with it. It automatically shuts down itself. I've read some of the articles of jac_goudsmit and other people, recommending to customize the casing. Add additional fans. But I did all of that. I actually took of the 2 bays. Opened the covering of NAS200 and gave a dedicated fan on it, bought a dedicated HDD fan. But still no luck. The previous user said, it didn't happened to him (he had his workplace air-conditioned). Will anyone give me some sort of advice? Thanks.
