Hi all, I'm trying to help a family member look for a new desktop computer and am really not having much luck. I've tried Amazon with limited success, and am hoping you guys have some awesome suggestion(s). Needs: Desktop PC (Macs are most-likely out of the budget) Windows 7 (or earlier) -- absolutely no Windows 8 Wi-Fi enabled CD/DVD burner 500+ GB hard drive Warranty available (at least 1 year, preferably 2+) Preferably a Lenovo, Asus, or good quality brand -- would really rather not have Acer, HP, or Dell (has had bad experiences with them). Already has a keyboard, mouse, and monitor, so those don't need to be included. Thanks!
