Round the back
The back of the Eureka is entirely fixed, with a generous PSU area up top, single molex-powered 120mm fan and six add-in card slots.If there is one thing that stands out on the back of the Eureka it’s the capability for water-cooling. There are numerous holes punched in the back plate for you to route cooling pipes, obviously according to your needs.
The two holes you see above the PSU area are just one of five pairs on the back of the Eureka. The only problem you will have fitting a water-cooling solution is just which holes to choose!
In addition to this, the PSU can be mounted either way around, a neat touch that allows flexibility according to PSU design.
Down the bottom are three more sets of water-cooling holes. It's strange to see this many on a chassis this size, especially as there is plenty of room inside the chassis itself for, say, a self-contained unit.
