There are. I can't find a manufacturer's site to check on that TECOM one.
Here's a bunch on NewEgg http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&Description=ide%20controller&bop=And&SrchInDesc=pci-express&Page=1&PageSize=20
A customer wrote "Cons: Included driver CD is pretty useless. Grab the latest drivers from Jmicron's site and use those. It uses a 363 chip. Drivers are available for Windows XP through Windows 7 64-bit and 32-bit."
Just do a little Googling or search Newegg. Find a PCI-E ide controller, read the reviews or specs to see if it works with Win7
Edit: There are also cheap converters to attach an EIDE drive to a SATA port. I don't know how reliable they are.
