Second unit bought from Xidax.
I find their units solid. First unit is 7years old. Operating in high temps. Has kept up really well. All games (Assassin's creed, Far Cry etc) play without glitches. All software doing just fine. One USB port non-functional, but eh. Started to slow just a bit and wanted an upgrade. So handed it down to someone and it is still working fine. (They will be using far less intensive applications.) Oh and the panel had come with a dent. Got it replaced free of charge.
New unit doing well out-the-box. No issues. Packaging was stellar. (It came a long way.)
Found them online while searching for something a bit...more. The highlights:
1) Customer service. Their agents are patient, helpful and not pushy. They may suggest a higher unit than what you had in mind, but they explain why and it is all verifiable. No gimmicks to try and rush you. Good responsiveness as well.
2) Good range of choices. With basement and refurbished deals
3) Cool freebies (linked to purchase price)
4) Frequent sales
I think they could do better with the instructions in the package and with labelling the extra parts, but likely most people buying from them know their way around.
I see comments about their warranty, but it's just one of those legal things you HAVE to read beforehand.
Giving high marks until proven otherwise.
Attaching a video. Sound is a standing fan. Unit is QUIET.
(Shane was an awesome customer rep. Above and Beyond must be his motto.)
