Hey Harmsway, I know how you feel. I actually put together a new computer just so I could play SH5 in all its glory. Silent Hunter was sitting on my desk for 2 1/2 months while I waited to put it together.
You might want to try
www.newegg.com or
www.tigerdirect.com and see about picking up the pieces yourself and have a local PC dealer put it together, or if you know anybody that's done it. The tricky part is making sure everything is compatible (I took a crash course on putting it together and what goes with what). If you are feeling adventurous to try and do it yourself
www.tomshardware.com is a great resource for questions about hardware and puting things together.
The system I put together I got from Newegg for about 1300$ but that was with a new monitor, keyboard, speakers, and a mouse. Newegg's shipping is cheap ($30ish) and I got everything within 3 days.
My system:
-AMD Phenom II 965 X4 (Quad Core) 3.4Ghz
-6 Gb RAM (2gb + 4 gb) Gskill DDR3 1333
-Samsung 1 TB hardrive
-ATI Radeon 5770 1gb GPU
-MSI 770-G45 AM3 Motherboard
-Corsair 750W power supply
-3 Cooling fans
-24x Samsung Dual Format/Double layer DVDR/RW
-21" LCD HD Screen (Probable went overboard with this one)
-NZXT Computer case
-Windows 7
