Just an update but my virtual desktop with graphics card passthrough is running like a champ
For normal browsing and work stuff, you wouldn't know it's not a seperate physical computer.
I'm up to 5 other VM's so far, lots more to build / move onto the box yet.
Also for info and I'd been doing this for ages with my G6 before but I run pfSense as a virtual router / firewall on the box. Make sure you give it priority over other VM's but otherwise it works fine. I can even play games without the ping really changing, even if another VM is loading up the CPU's. I do love ESXi
So in actual fact I could have the benefit of 2 NICs and ILO without adding a PCIE NIC (which would cause noise issues based on the above posts)?
Yeah that's right. iLO shares NIC 1 (Can probably change that in the BIOS, I've not looked). So you can still use both of these NIC's for other stuff.
As mentioned there is a 3rd NIC already on the motherboard, just no connector for it. You can get the connector for about £20 + VAT which gives the iLO a dedicated NIC of it's own. This would normally be used for bigger installations that might want iLO traffic on a seperate switch / VLAN. For a home install, there's no point to this really.
I can confirm the fans are not very consistent on my server either and it's certainly more annoying with a PCI-E card installed. I've finally got around to putting at least near (well, on top of) my rack under the stairs so it's not a problem any more. I'd not want it in the same room as me, especially a bedroom.
The fans all use a custom connector and I've read the BIOS is very sensitive to replacing them with lower RPM versions.
Glad it's not just mine then and that's a standard thing. There's 2 options in the BIOS, Optimal Cooling which I think it's on which just runs the fans fast enough to cool it to what it wants or another option I forget but which I believe will run them faster most of the time. I've not tried it but I imagine that would stop the tweaking of the speeds slightly at the expense of more noise... Either way it's not ideal, I'll probably just force myself to get used to the fans going up and down slightly.
Also I wasn't aware the fan connectors were weird. I just thought I'd been out of the building PC game for too long as when I started you didn't even connect them to a motherboard. Then there was the 3 pins and the last I remember where 4 pins so it could more finely control the fan speed. These have something like 6 / 8 cables (Forget now what it was when I opened it the other day). So clearly it can tweak the speed just slightly. A skill it annoying does a lot
