@DZMM
Thank you for your repoonse.
All the hardware is used. I have essentially scraped together free stuff from different places. The SSD's are intended for speed. I will include a parity disk. The PSU is standard for the Dell T7610. In time i will replace the disks, one by one, hopefully before failure.
I don't game a lot, but I would like to do some gaming if possible. Do the disks have to be the same size?
Thanks.
