poblatu,
Follows is an idea for a workstation intended for 3D CAD. The basic recommendation is to have an LGA2011 processor as these have a wider bandwidth, more memory, and more PCIe lanes than 1155, but especially offer the possibility of 4,6,8,10, and 12 cores, extending the useful life of the system by upgrading. The choice of options depend on the specific uses, for example, if one system is mostly 2D, the graphics card can be the lower end, but fro intense 3D the higher end GPU, and if there is a system used for rendering and presentation image processing, both the 6-core and higher end card will be an advantage.
In a business situation, there are a lot of advantages to buying system from Dell, HP, or Lenovo with on site service warranties. I don't know any architectural, industrial design, graphics, or animations firms using self-built systems, unless there is a more or less full-time IT expert. the advantage to building is being able to tailor each part to your uses, plus considerable cost savings. The $1800 E5-1650 V2 system system below as an HP z-series would cost at least $700- more. Still, the following might be considered from a standpoint of specification.

1. Xeon E5-1650 V2 6-core 3.5 / 3.9GHz, 12MB cache, LGA 2011 (Passmark CPU score= 11462, rank = No. 12) > $630. (Superbiiz) (Having an LGA 2011 has a much wider bandwidth than LGA 1150 and will allow you to upgrade to 8 and soon 10-core)
1A. OPT'L CPU Intel Xeon Quad-Core Processor E5-1620 v2 3.7 / 3.9GHz 0GT/s 10MB LGA 2011 CPU, OEM - CM8063501292405 > $298. (Superbiiz) (If you are not going to be doing much rendering, this could useful CPU- quite fast, economical- LGA 2011 Zeon E5 at a E3, LGA 1150 price)
2. Noctua NH-U12S 120x120x25 ( NF-F12 PWM) SSO2-Bearing ( Self-stabilizing oil-pressure bearing ) CPU Cooler $70
3. ASUS Z9PA-U8 LGA2011/ Intel C602-A PCH/ DDR3/ SATA3/ V&2GbE/ ATX Server Motherboard > $287.
4. 16GB (2X 8GB) 240-Pin DDR3 SDRAM DDR3 1600 ECC Unbuffered Server Memory > $150. (Check ASUS motherboard compatibility list)
5. NVIDIA Quadro K2000 VCQK2000-PB 2GB GDDR5 PCI Express 2.0 x16 Workstation Video Card $420. Quite good in 2D and adequate in 3D
5A. OPT'L GPU__ Quadro 4000 2GB A better card in 3D than the K2000. Buy "New Other" on Ebay for about $400.
5B. OPT'L GPU__ Quadro 5000 2.5GB A better card in 3D than the 4000. Buy "New Other" on Ebay for about $550. Workstation cards are not screamingly fast with games as they try to finish each frame. Of the three listed, the 5000 would be most capable in games.
5C. OPT'l GPU__ Quadro K4000 3GB Very good in both 2D and 3D CUDA acclerated and OpenGL applications. About $750 new.
5D. OPT'L GPU__ Quadro K5000 (4GB). In my view the perfect GPU that does everything beautifully > images, 3D video processing- and would be useful for years and years. However, $1,800 new and used still $1,200 or so. If you are doing though large 3D infrastructure models, your firm might consider having one system with this card.
6. Western Digital WD1003FZEX Caviar Black 1 TB SATA III 7200 RPM 64 MB Cache Internal Desktop 3.5" Hard Drive) > $93 (This is the new single 1TB platter design- very fast.
7. SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply $120.

Other options >
1. I don't think SSD's are strictly necessary for workstations, but they do have advantages if you're using / transferring large files like video. If adding an SSD, I'd suggest one that could hold the OS, all programs, and the current files and then use thee mech'l drive ro storage, / backup, and keep a system image for quick restore in a partition.>
Samsung 840 EVO Series 250GB 2.5 inch SATA3 / SATA 6.0 GB/s Solid State Drive > $179.
2. If your systems are quite elderly, don't forget to consider suitable monitors and I'd recommend (if budget allows) 27" ASUS, Viewsonic, or Samsung @2560 X 1440. I strongly recommend that you see these in person, paying special attention to the coating, controls/ calibration, backlight bleed, and small text quality. Autodesk applications throw up hundreds of menus with tiny-tiny text! These are not cheap, but the size and resolution saves dozens of pans and zooms per day.
