Am I doing this right?

[sneaky_peet]

Hi all,

Ordered a Syrenis from Terahash in April but since that is not moving, I need to look for alternatives. I had this quote from a local supplier. Any remarks/feedback?

1 Supermicro SYS-4028GR-TRT2
2 Intel Scalable CLX-SP 4210R 10C/20T 2.4G 13.75M 9.6GT 2UPI 100W 3647 P0
2 Samsung 32GB DDR4-2933 ECC REG DIMM 2Rx4LP M393A4K40***-CVF
2 Intel S4510 480GB. SATA 6Gb/s. 2.5'' SSD. 3D. TLC. up to 2DWPD SSDSC2KB480G801
1 Supermicro MCP-230-41803-0N Top cover for SC418 with GTX card support
1 Supermicro 3U Railkit L Edition For 842TQ MCP-290-00057-0N
4 RTX 3090 
4 Supermicro 8-pin to two 6+2 Pin 5cm Power GPU Cable CBL-PWEX-1040

Furthermore, what kind of OS should I be running? I assume some kind of Linux flavor is best but which distro/kernel has best driver performance/stability? 

Stupid question maybe, but what bout SLI? I guess SLI doesn't matter when using hashcat?

I don't know if you have worked out your hardware acquisition but I would be tempted to give this company a try:

If you do end up doing that, make sure to post your experience here! We too have had some issues regarding vendors and have ended up purchasing our own rigs, but I was really intrigued by the offering from Comino.
