well if its your first attempt, it is a bit hard, my sata cables are the best i think, as for the rest or the case you need some tools LIKE PIN EXTRACTORS to remove the molex plugs for the main cables of the power supply, as soon as i get all the pictures done of mine then i will redo the guide. also rule of thumb for heat shrink is, it shrinks to about 50% of the stock width. that is why i did the sata cables in the guide to give people a chance to do it on something easy, also another thing that is easy is the fan wires that connect to the mobo via 3 pin connector, there small enough to work with and easy to get the pins out using an x-acto knife if needed.
