Performs like a champ

Pros: 8 cores, 16 threads, 65w TDP, near silent stock cooler in the Wraith Spire.
Cons: Most AM4 motherboard have some teething issues as kinks get worked out. Uses pins, I guess.
2 of 4 were DOA

Pros: 8GBs, Fast, stylish black heat spreaders.
Cons: 2 of the 4 DIMMs were DOA. Any attempts to install them results in Memory Not Installed errors on my board. The other 2 DIMMs worked great though.
Overall Review: RMA for replace is in progress right now, so hopefully I can bump this review up to 4 or 5 once I have 4 working DIMMs.
A nice little Windows 11 tablet, lot of bang for buck

Pros: Its light weight and decently spec'd for the price. Note, check the model before you buy, they have a different CPUs in the product line. The model I have has the Celeron N4120 and 8GB of LPDDR5 RAM, with 128GBs of storage. I would consider 8GBs of RAM the bare minimum for Windows 10&11. Performance is in line with what you expect from a 4c/4t 6W sku.
Cons: The cons I experienced are not with the tablet itself, but a byproduct of Windows 11 and Microsoft. First, bypassing the MS account login requirement is harder on the tablet than a traditional desktop or laptop. I got around this by signing in with my outlook account, then creating a local account, setting it as an admin, then deleting the MS account. May or may not be an issue for everyone, but Win11 requiring this is incredibly annoying. Second, the Windows 11 Home install comes in S mode, locking the user to only installing applications from the Windows Store, which will require a MS account. Windows Store has always been a unusable mess. You can flip Windows 11 out of S mode relatively easily, but it is a one way switch. S mode only improves performance and security by severely limiting what the user can install.
Overall Review: Assuming you have a use scenario for such a device, and are willing to jump through a couple hoops to unkink Windows 11, then I would recommend the tablet.
Tiny but mighty

Pros: This was a lot smaller than I expected, maybe half the size of the DeskMini 300 it replaced. I purchased the Ryzen 5 5500U model, with 16GBs RAM, 512GB storage, and W11 Pro. It drives my gym TV through the HDMI perfectly.
Cons: Somewhat noisier than expected, even in the 15W default. Its a non issue when playing videos while I'm working out, but if it was sitting on my work desk, it'd probably be an annoyance. I dislike the hoops I have to jump through to get Windows 11 up with a local account these days, but that's not related to the PN51.
Overall Review: I would recommend this to others looking for a tiny but potent PC.
Fastes AMD card available in Aug 2021

Pros: Easily maxes out every game in my library at 4K resolutions, with some older titles barely getting the card to 1/4th of its top clocks.
Cons: Big, really really big. Double check your case measurements, it was a tight fit in my Focus G case with the drive cage installed. You also need 3x 8pin PCIe power connectors to feed it. The price is also a big con, being inflated to nearly double MSRP.
Overall Review: Also not as loud as my previous 5700XT either, even when I force it to 2.4Ghz core clocks.
An excellent cart for 1080p -1440p gaming

Pros: Powerful performance, single 8pin PCIe, consistent boost clocks, stable
Cons: Takes up a bit more space, will object more than just the adjacent PCIe slot.
Overall Review: Purchased this card as an interim card since my more powerful GPU waits for an RMA. I didn't expect this card to excel at my usual 4K gaming, but I've been pleasantly surprised by its capabilities. Outer Worlds at 4K on High presents is perfectly playable with frame rats consistently above 35. Could go to the Very High or Ultra presets if you were willing to lock to 30. Likewise, FarCry 5, New Dawn, AC Odyssey, and others are all playable at 4K using Normal/Medium presets. Now, this card wouldn't be my first choice for 4K gaming, but it really illustrates has accessible 4K gaming as become.
It was definitely a PS5
I had some concerns that it'd be a box of bricks, but, it was actually a legit PS5. Expensive, but it was legit.
