I built a system about 4 years ago with a 6700K on a Z270 micro board with 16GB of RAM and a 250GB Samsung 960. The user was adamant about keeping the Windows 7, which I painfully migrated from an older computer. Now Windows 7 is obsolete and I'm thinking about the upgrade plan. There are fewer choices now in mATX and none with 4 PCIe slots like the old board. If I get the Z590M board like the MSI MPG, can I have the removable SATA drives in the BIOS as with my AMDs? (The manual is rubbish.) I was using an add-in card for the 2 bay drives in the current system. It's either that or maybe lose the internet Ethernet, sincer I need an RJ45 for one NAS. The other NAS would be on the Aquantia SFP+ controller (4x) PCIe 3.0. Are there any limitations on card use in the first slot that is usually for video? I would be using the 11700K and some kind of reduced capacity Nocturnal cooler that fits the 5' height case. Thanks.
