Going to order myself one of these with the guys who have had one of these how do you rate them and which one.
I've got the 800D and I love it. The C2 is technically superior and can hold more WC kit, but doesn't display your hardware. If air cooling, go for C2 as it's much more suited. If you're WC'ing, then it's a hard decision. There's pros and cons for both. I prefer the looks of the 800D, but recognise the talent of the C2. Both are excellent and you'll be disappointed with neither.
I'd say get a C2 and mod the side panel to have a small window above the side fans, a friend of mine did that and he loves it.
