i know it's personal but why have a dvd write and a reader? thats fine if you like but it seems unnecessary and just adds extra cables. splitters are fine though BUT, if you have three hard drives you might want to consider a power supply unit that has three fans, one to extract hot air from inside your pc. they are more expensive but they will be worth it in the end, and you could get one with more power leads for all those drives. if they dont have any on ebuyer or microdirect (the best two component shops in my opinion) try a specialist overclocking shop, just do a search for overclocking. if not, try click here, they have lots of specilist stuff too.
