I have bought 3 of these, separately, to make a server cluster. They are all slightly different; some are Type AX and some AY. Two came with G3250T CPUs instead of the listed G3220T. Two came with USB Wifi adapters instead of the integrated Wifi; I'm not using Wifi so it's not a deal-breaker but it is misleading because now you lose a USB port. All of them came with severely outdated BIOS and Intel ME firmware. All were missing a few internal drive bay retaining screws. One came with a random third-party power supply, which I did not appreciate. The HDDs are very slow so swapping them out with SSDs is essentially a must.
