I used to build and service computers as my business. I'm retired and getting rid of things I don't need anymore. I have a computer that I used for testing disk drives, recovering data, removing malware from clients computers and a variety of other things. It's too old for Windows 11 but will run Windows 10. There is no operating system installed or storage device. The motherboard supports a NVMe drive so you can still get good performance if you are just using it for internet access, email, etc. The case has a DVD drive. Most of the new cases don't support DVD drives. There is room for 5 disk drives. There are front cooling fans for the disk drives. I have a LSIMegaRAID SAS 8341-8I card for free if you want to have mirrored drives. I have some server drives that are still good and don't have that many hours on them. The case will take any motherboard up to an ATX which is what is installed now. This is what's in the case:
Processor Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz
Installed RAM 16.0 GB
Graphics Card NVIDIA GeForce GT 710 (2 GB)
