NK 4.0 build help

Hi So heres my list of starting kit:

SuperMicro X9SCM-F Motherboard System Board Rev 1.11A With 16Gb RAM
Intel Xeon E3-1270 V2 (SR0P6) 3.50GHz 4-Core LGA1155
Samsung 860 EVO MZ-76E250B 250GB Internal (2.5") SATA Solid State Drive SSD New
WD40EFRX WD RED 4TB 25MM 6G SATA 5400RPM HDD incl.20% VAT FREE Carriage

I will want to expand the hard drive capacity, so looking at a descent case… maybe something that can hold 10 drives… any recommendations on case and card that can help support this… any other recommendations welcomed

do you want a rackmount case? or a tower case?

Sorry looking at tower… any recommendations for cards to help expand the drive capacity

Were the options that are outlined in the guide insufficient?

Sorry not that… I have an idea on case but I need to find the right card that allows for drive expansion, via PCI maybe
Also can I ask of the build so far looks good…

LSI HBA + expander will cover it
