Pros: I think 4 bay units are a better deal than two bay ones. You spend more for the NAS itself, but you can save money on the hard drives using lower capacity disks, and still get the same overall storage space. Check the math for a 6 TB RAID 1 array (two disks of 6 TB) vs. a 6 TB RAID 5 array (three, 3 TB drives). And with a 4 bay unit, you have a spare slot to upgrade. This 4 bay unit has a powerful, energy efficient processor. It will run Plex. (Have not tried it yet, but that was a compatibility point for me.) 2 GB RAM, which is plenty for a Linux based server. Responsive user interface with lots of apps to choose from. The processor is made by Intel. This might be a factor down the road when the product reaches end of life. Switching to a standard Linux distro could be easier. No plans to do that until I have to.

Cons: * Drives cannot be hot swapped, but if you are doing a lot of that with a NAS, you are doing something wrong. And most units that have hot swapped drives do not have lockable trays, which is also not good. The ones that do cost a lot more. I'd settle for a door covering unlocked trays, but even that is hard to find. * Memory cannot be upgraded, but again, 2 GB is plenty. * So I guess there are no cons from my perspective.

Pros: - 6 Zen 3 cores good for 12 threads - best integrated graphics you can get - PCIe boot drive with large mechanical HDD - wireless connectivity (I didn't notice this on spec sheet but it is in a picture) - honest to goodness 65 watt TDP, so no heat and very quiet - Windows 11

Cons: - 12 GB memory which prevents dual channel mode operation. This matters if you use integrated graphics for gaming, otherwise not so much. DDR4 is cheap right now, so why not upgrade to 16 GB (2 x 8 GB) or even 32 GB (2 x 16 GB)? Other minor cons: - PCIe drive is 256 GB. 512 GB would be better - No DVD drive. One picture shows the computer with a DVD drive, the specs sheet says otherwise. - Custom motherboard. It won't work in a standard case, though you can take the components to a new case. - Windows 11 (just not a fan yet, but it's time to embrace the future)

Overall Review: I bought a refurbished unit and at that price this is a smoking hot deal! Initial impression very positive. Looking for a reason to buy another one.

Pros: 8 cores, 16 threads, 65W thermal design power Mic drop!

Cons: Absolutely none.

Overall Review: You can't go wrong with this. Do you NEED 8 cores and 16 threads? Probably not. Do you WANT 8 cores and 16 threads? YES, you do! Low thermal design power. Can even put it in a previous gen AM4 motherboard if the BIOS supports it. That will save some cash. Comes with a perfectly fine CPU cooler.

Pros: Wraps an SSD in a 3.5" drive form factor so you can put it in a legacy case. Has side mounting holes AND bottom mounting holes (which I needed for my case). No active cooling, which is fine for an SSD. No extra power connector needed.

Cons: Opening the case was a little tricky, but you only do that once.

Overall Review: Definitely recommend this over other tray style adapters you can buy to mount an SSD. The big advantage is that this has all the mounting holes of a typical 3.5" hard drive.

Pros: Allows you add/remove two 2.5" hard drives without cracking open the case. Solid construction. Installed easily. Plugged in a drive and it appeared on the desktop no problem. Comes with all necessary cables.

Cons: None so far.

Overall Review: Not many cases have exposed 2.5" drive bays now. For those that do, this is a fine product.

Pros: Decided to upgrade my current rig rather than build a new one. After a bios upgrade, it's a drop in replacement. Could not have been easier. Stock heat sink is good, not great. Have not tried over clocking yet. What am I going to do with all those cores?

Cons: None.

Overall Review: It's a 5 star CPU, but there are some caveats. I don't believe Turbo Core works with the version of Linux I'm using (Ubuntu 10.04). I turned it off for now. An upgrade will fix that.
