Review on StarTech.com Native PCI Express Combo Card: 2x Serial 1x Parallel RS232 Adapter (PEX2S5531P) by Charles Chambers

I thought I would have to buy two expansion cards but this has made my life easier. I installed this in my Vostro 230 Slim Case and it works great. comes with drivers and the quality is higher than i expected. It comes with optional risers to match your slim tower design. All you need is a small wrench to remove the bolts holding the riser and install smaller ones.
