This is the third HP mini I have seen renewed by Amazon. The first is a G3 and is very good. The second, a G4,  was awful and sent back, the OS was corrupted and physically very sloppily renewed. This G5 is great, everything fell into place nicely and is now running Windows 11. It did not come with a HDD caddy. A nice touch is that the 16 gigs of ram is in one module. I believe that buying renewed computers is a bit of a crap shoot, some will be bad, and will need to be sent back, but most will be good, in need of a little work, but well worth the effort. Do your home work, check which CPUs will do Windows 11. Read the listing carefully, plain "SSD" is likely a off brand SATA device, etc. good luck
