Hello!
I hate to hear that your hard drive died. If it is a SATA drive that failed, or if your computer has internal SATA ports, you can get a 1 TB SATA replacement for $80 or less, and a 2 TB for a little over $100. Hard drives are not too terribly difficult to install, and it's not like you need an OS transferred fro the old drive.
If you're willing to go as high as $500, you can get a nice desktop AND LCD monitor (bundled or separate) for that - usually less WITH Windows 8.1 pre-installed, It's a matter of whether you choose to buy it locally or through someone like Amazon, Newegg, Tiger Direct. etc.
One thing I definitely recommend is that when you get a new PC, create recovery DVDs (you'll need several blank ones), in case something happens if/when you try to add Linux Lite to it. PM me if/when you get a new PC - so I can advise you on how to make it run better on the Windows side - ESPECIALLY after you add all those Windows updates. Even out-of-the-box, new PCs ship with hundreds of invalid registry entries in them...
