Got new PC few weeks ago...
-Intel i7 2600k
-ASUS P8Z68-V Pro
-2x ASUS GTX560Ti
-2x Kingston HyperX DDR3 4Gb 1333Mhz CL7
-OCZ 60GB Agility 3 Series SSD / SATAIII
-Seagate 1TB Barracuda 7200.12 / SATA III
-Nice collection of older HDDs, from 1TB to 250GB / SATA II
-LG Bluray optical driver
-Front panel fans are all Noctua, two 140mm and the NH-D14's 120mm "front-fan" is on the front panel.
I tried to manage the cables as well as I could and got 'em pretty decently...
Later on upgrading another 8GB of RAM and buying few more Noctuas and maybe another 1 or 2TB HDD, as I'm building a server soon so I don't need so many HDDs warming the case, just few TBs for storage etc... Everything else, not so much used pictures/videoclips and so on can stay on storage-server as you could imagine.
Propably making the rack-case for this PC, server, another PC and UPS which I might be buying, we'll see...
