We've been wanting to do a mini-ITX build for quite some time. Our original plan was to keep the budget on the lower end, but after looking closer at the case I couldn't resist bumping up to a more powerful system.
Corsair kindly sent us the 250D to build with, and for a mini-ITX form factor it was excellent to work with. When all the panels are off, the interior is very accessible. It was only once we got the radiator installed that things became cramped. A quick note on the radiator - we wanted to use the H105 cooler, but it is too deep. Only the H100i would fit.
We already had the i5-4670K and 780 Ti on hand (and hadn't done a build with them yet), so we decided it was time those made an appearance. If this were going to be my daily driver, I'd replace the 1TB drive with something larger. However, we have several of the 1TB drives on hand, so that's why that was included.
