An r720 from dell or similar model from dell with 600GB*2 SSD intel s3500DC model, 20 cores & 256GB of RAM will go for 5k-7k. You can bump this to 386GB of ram without going above 10k.
When I changed the country to Japan, the sticker price jumped from 2000 USD to 15,000 USD eq. for a very basic system. I am just at a loss as to what can explain this disparity. Guess I will have to call up my vendor to get a comparable quote.
My tip is always to try to get in contact with a couple of reseller and play them out against each other in the price department.
If you are looking for larger purchases 50k+ USD than you should talk directly with Dell, HP or comparable vendor and put them into the play off for who you choose :)
