It is as usual, salesmen selling you what you do not need. One of the best examples, Zeiss is selling Z840 for their basic wide-field system, where there are only two USB port are utilized, one for the microscope, and another (via PCIe x1 USB 3.0 port) for the CMOS camera. Z440 is an overkill for Zeiss wide-field system. But Zeiss is "smart" to profit from you "doing nothing". If you need speed, just buy a USB3.1 PCIe x4 card, but likely you do not need it. Do not waste money on RAID for data acquisition, GPU is over quoted, nVidia P2000 is more than you need, unless there is on-fly deconvolution, then P4000 should be good enough. 64GB of fast DDR4 memory is enough. What kind on memory is "hidden" under "512 gb of memory"? You may need fast NVMe SSD for data caching, again likely NOT during acquisition. ZEN could be less dependent on Windows 10 (rather more independent), but Zeiss has to learnt it yet. For data storage, just attach DAS box with LSI x8 MegaRaid controller to acquisition or image processing workstation with 8-16 Enterprise edition 8 TB hard drives in RAID 10 for transient data processing, or RAID 6 for long-term storage. If you have any questions, please contact me offline.

How fast are you acquiring data?
Entry level SSDs are about $120/TB (~1GB/s write) while high
performance SSDs are $250/TB (~2.5 GB/s write). Since SSDs are very
inexpensive, that $6000 is probably getting you more than just a
couple hundred dollars worth of disks?
