My current one is a
Thermaltake Matrix VX, which is modded slightly to accommodate different fans (Swapped out all stock fans with Noctua 120mm's, and cut away parts of the aluminium framework in order to get a more uniform airflow).
My current project is refurbishing and modding a
Thermaltake Kandalf LCS, but need new parts for the liquid cooling system due to the old CPU-block cracking and thus causing a rather spectacular short of my old motherboard and vidcard. Also have other plans for the Kandalf in terms of modding, but that'll have to come after the LC-parts are aquired.
