My current HTPC is a Dell Optiplex 755 running Mythbuntu 9.10. I have to give back the PC (it was borrowed), but I can keep the video card and sound card, both of which work great with MythTV. I want to get a replacement PC without spending a bunch of time shopping for parts and building one up from scratch, and without spending more than $400 or so.
So I'm just looking for suggestions for a simple pre-built system that'll make for a quick, compatiple MythTV setup (I'll probably do a clean install of 10.04). I checked a few sites and frankly didn't see anything much cheaper/easier than the Dell Inspiron 570 for $379 new, but would love to hear of better choices (esp. one that doesn't come with Windows - I hate paying for it if I'm not going to use it).
