Saw you at JCat forum. Good!
BTW, since you have several aftermarket PCs, why don't you try for yourself? Choose the PC you deem makes the least impact in your system now and replace it with a generic PC. Get used to the new sound. Then use that aftermarket PC for you linear PS and listen for changes. Cheap and easy test, and you can see if it makes a difference in YOUR system. That beats all others' opinions.
