The 15cm 90 degree SATA 15-Pin Splitter has came from eBay, but it isn't that good that I thought it will be. But finally I have enough USB 2.0 ports now thanks to the Low Profile USB2.0 Female Back Panel to Motherboard 9Pin Cable with PCI Bracket, and now I don't need to worry about the overheating of the RAID Controller Card thanks to the 14mm Small Black Anonized Heatsink, and I got more 2+2GB RAMs for $25.
System: Lenovo ThinkCentre M91p*
Processor: INTEL Core i5-2500 3.30GHz

(*this is the $300 system, what I show in another video, with more RAM)
