★★★★★Defective
Got a defective part from Best Buy, and only really acted up after the 2-week deadline for the motherboard for me to refund it. Be very careful of what you order here!

★★★★★Looks nice. So far so good.
[Employee of bestbuy] Solid board. Pros: Good power delivery design. No coil whine as far as I can tell with stress test. Looks great. Sturdy. Minimal on board RGB. Easy install. LOTS OF EXPANDABILITY. Top m.2 slot shares lane with PCIe 5 x16. Other two slots each have their own separate lanes. Easy detach for beefy GPUs. Straight forward BIOS and EXPO enabling. 5 year warranty. Out of the box support for Ryzen 7800X3D so no need to flash the BIOS. Cons: Kinda pricey but what isn't these days. Box does not come with security seal so I can only assume this one hasn't been opened. The first one I ordered had divots near the opening flap that made me second guess if it was opened before or not.
