My set up has evolved over time and had a few hicups, (when I change stuff, and nothing bad)
My PS always works, The screen is great. The keypad is fine. I have a simple set up:
Celeron 300a integrated MB, Desktop HD, a keypad and 14 inch LCD desktop. I only play music and use W2k as an OS.
My deck has RCA AUX in so that is simple also.
Parts of the system have been in use for more than 4 years, no PC hardware failures. The drive has the longest service time.
