Pros: – Inexpensive, compared to other solutions
– Includes the hardware for mounting drives and board Cons: – The chassis is a bit flimsy. I don’t have faith this will be able to hold it’s own weight for too long. Overall Review: I bought a 2U Rosewill case for a server a few years ago, and it has held up decently. It was a bit thicker on the rack mounts and still managed to start sagging, though. I will be reinforcing this unit to prevent it from doing the same.

Pros: Low cost rack mount case Cons: Not quite long enough for full length graphics cards (hard drive rack interference)
Cannot use expansion card hold down panel with graphics card
One quality issue – power/reset label applied upsidedown
Thin metal construction Overall Review: For my needs this case did the job. This was a new build and the first time I decided to use a rack mount case. Motherboard and powersupply fit fine and there is reasonable space under the hard drive rack to tuck away any extra power supply cable length. Hard drives (5 1/2″) in rack overhang the motherboard a little, but there are plenty of bays to avoid real issues. Fans are quiet and seem to give decent airflow.

Pros: I like the look but they missed the mark on quality and execution. Cons: HDD mounting brackets bend under weight of hard drives. (9 mounted). Cheap construction, very flimsy. You get what you pay for. Sides of case try to cave in under weight of hard drives. Overall Review: Junk

Pros: Shipped fast Cons: Have to leave the middle section open so you can plug the power connector into the MB. You won’t fit 11 3.25 drives. Not enough room…all they had to do was move the drive assembly 1 inch closer to the front. Theres no way to dress the cables in cause theres no room.There’s a difference between cheap and less expensive….this is cheap. Overall Review: I wouldn’t recommend this case at all.

Pros: This chassis has a decent amount of room to build and and a drive shelf that can hold a ton of drives. It can fit standard ATX components which is good for homelab builds if that is something you are into. Cons: The construction of this is super cheap and it has basically no quality control. I ordered the case and then built in it about 2 weeks later. By the time i started building in it i realized just how bad the quality control was but i was on a tight schedule so i had to build in it anyway. if i had checked it as soon as it arrived i would have returned it and bought something else.
One side of the drive mount had no screw threading for mounting. at first i thought it was stripped but on closer inspection i noticed it was never threaded in the first place. it was just drilled holes with nothing for the screw to bite on. i got around this by adding my own bolts with nuts to secure the drive cage in place. the rivets all over the case were not tight making some of the mounting points have play in them. Only a small number of the motherboard standoffs are installed, and you will have to install the spares that come with the case if you want to mount a standard ATX board. except… none of the standoff holes were threaded either. i had to use the standoffs to cut their own threads and it was terrible. The RESET switch connector for the motherboard was somehow wedged between the front panel and the bottom panel making it completely inaccessible and the bottom panel was imperceptibly bowed upward because of it. i didnt notice this until i started building in it. at first i thought maybe it got banged around in shipping and and got wedged in there. but the front panel has literally 0 bend to it so the only real explanation is that it was stuck in there when the front panel was riveted onto the chassis. the only way to get it out was to cut the reset switch connector and then i had to solder a new plug head to it. absolutely unacceptable. The case does come with a ton of spare screws and motherboard mounting posts but all the different screws are in the same little bag making it a huge pain to select the correct type of screw when building. Overall Review: Do not buy this case. I regret ever using it. If i had had more time i would have returned this and bought something different.

Pros: looks good on a rack Cons: Thin and weak metal material
Unreliable connectors
Burned out LED’s
Slot mounting holes without any threads
Uneven corners/different height Overall Review: I cannot emphasize the utter disappointment that this case has proven to be
It is made such thin material, that the case twists and buckles with ease
The threads are made of cheese and will strip with even the faintest tension
The power LED DOA, and the HDD LED last about 2 months before failing
One of the front fans died within 2 weeks of being turned-on
The drive cage bends under load, with just 1/2 of the HDD’s installed in it
The drive cage retainers, have bent and broken
The retainers which are riveted into very thin walls, will work their way through the side walls
Seriously, I cannot stress how horrible this case actually – and moreso, that should not be sold on the marketplace

Pros: Inexpensive rack made of pretty solid material. Fits a good amount of storage in it. Cons: Pretty tight and not the easiest to build in Overall Review: Definitely recommend this for a basic server
