For the case I actually think it’s a fair price for the product. The problem is the product is not a good fit for the homelab market.
The markup on everything else is absolutely insane though.
Also competing with used gear that is going through e-recycling facilities is going to be hard for them.
They made a good product but missed the mark imo.
What’s your budget?
If you can, spend an extra ~$100 to get at least an R730 imo. You will get more performance and the $100 will pay for itself in power savings in less than 1 year.
Looks like both of your formulas are the same?
To your question: this may be a lot of fun to play around with, but it will costs hundreds of dollars per month to leave on 24/7. For comparison: that power is more than what it would take to blast your AC all month in the summer.
If you search you should see the error only effects a few features and not all of iLO.
And iLO is needed the same way a homelab is needed. sure is nice to have though
Plus hardware pass through makes moving VMs more complicated. More virtual disks and networked storage for everything reasonable
I have not found L2 ARC to be much of a benefit for most of the time.
How many disk bays does the system have and how much storage to you need?
May not be a bad idea to make an HDD pool as large-volume backup target and a an SSD pool for data you want to store and access remotely
