Pros: dont let other reviews fool you. You don't have to buy HP drives. The HD cages use special screws (star) but other than that the Hard drive fits fine... after all they are all standard size of either 3.5" or 2.5".

Been using these servers since G6 and I can't say enough great things about em. Spend a little money on three 6tb hard drives and one 256GB SSD. They all fit great in this server. One of the other things I like about these proliants is they are scalable. Granted you buy HP parts you can scale these servers up to support a lot of different configurations.

Cons: HP Parts can be expensive. If you didn't buy support or ran out of support, replacing components can be very costly.

Other Thoughts: the Motherboard RAM DIMMs are built a lot more sturdy than the G7s. I use this server at home to run Windows Server Essentials and PLEX Media Server and it runs flawlessly. I upgraded memory to 16GB and added a SSD for my OS.

Pros: sleek, sexy look. lots of air flow, separate cage for SSDs and 2.5" HDs. room for large graphics cards, removable mobo tray and it turns into a testing bench!

Cons: case is a tight fit. I found it difficult to reach in there and tie down cables.

Other Thoughts: Backplane fried a TB drive because the molex power connector in the back accepts the molex connector any direction. this means if you plug it in upside down, you will reverse the electrical flow causing your drive to short out. Was pretty annoyed I didn't pay closer attention to this.
