I am running Win 10 Pro on an Intel Core i7 4770K CPU. I have an external 5 bay SATA cabinet with about 40T (four 10s and some change) and need to expand. I do not need RAID or anything complicated or "stylish". A cabinet with maybe 10 or more bays, fan cooling, a power supply, a few LEDs for troubleshooting and I'm good to go. I would like to stay away from units that require proprietary hardware etc. Price is a factor but will not get in the way of a good, long term decision. That being said, I don't want to spend $1,000s on a pro rack mounted cabinet. A priced right, rack mount is OK though. I'm asking for suggestions on a cabnet only, used is definitely an option. Thanks in advance.
