BTO PC's
You have to answer more questions setting up an OEM PC nowadays than a vanilla Windows 7 install. Plus all the time saved not building the computer is lost uninstalling all the bloatware. I'd say it takes me less time to assemble a computer and get Win 7 installed than it does to get an OEM started and cleaned out.
You can still use iTunes in Windows so all that Apple Lossless is still fine. As far as maintenance issues go a custom built PC with good quality parts will likely have far fewer than an OEM.
This is definitely the way to go. Also stay away from Dell. Not that other brands are built any better. It's just since Dell often uses proprietary motherboard form factors. So if a it is out of warranty and being repaired you can't get a standard ATX board in there.
If you buy a consumer model steer clear of Toshiba. They really load up your computer with crapware.
There are a couple of companies out there that will build custom PCs (with or without OS installed) e.g. Cyberpower. You can also power build a Dell.
Bottom line though...
A 27" wide gamut IPS display is going to set you back $1K add a i7 desktop processor, 16 gb ram and a SSD with a strip set for speed and a good high level graphics card AND add a 3 year warranty from any Vendor (~$200-300) and you could have just bought an iMac AND have a magic pad and magic mouse. I have sold over $8m of Dell hardware in the last year. We sell Dell to the enterprise but we all use MAC's. The best of all worlds with VMWare Fusion installed and Win7/Lion/Linux and a sigle box replaces three others. The MACs are not really more expensive. A Ultrabook equipped like and Air is within $150.
Go to Cyberpower and build a PC that matches a well done BTO iMac27 and the gap wont be huge. If you are doing photography what you need to be most concerned with is the visible color gamut your primary display uses and how well you are able to match it to your your print profile.
