Only Xrumer on server?

So I already own a private box at hostgator with all my whitehat sites.

So my plans are getting xrumer in about 2 months. I'm been looking around for some offshore hosting to run the xrumer and found a few options.

My question is if I should leave all my sites and stuff at my hostgator account where it already is and just leave xrumer on the other server, or if its ok to put all my whitehat sites on the same offshore server as xrumer?

Also another quick question... whats better for running xrumer, windows or linux server? And while I'm at it, which server is better for running LFE? Sorry if its a dumb question but when it comes to severs and hardware and stuff I know nothing.

Thanks

Xrumer only runs on Windows. LFE can run on either windoes or linux afaik.

I keep my xrumer/blackhat stuff on a different sever and separate from my whitehat stuff. Also xrumer runs only on windows.

xrumer needs windows. Though there is a way of installing xp on ubuntu, thats more hassle to save some bucks.
I would keep white hat sites and xrumer seperate. Apart from the site safety, it will also give xrumer more room to fire.

Ok, I'm gonna keep my box at hostgator with LFE there and get a separate one just for Xrumer. Thanks for the answers guys,
