I'll add some extra info about the T7500 -
1. I have one running 96gb of ecc ram for CAD/Revit and though revit is slow on any computer, its actually quite nice to work on, on this one.
2. It has a build in perc6-ir controller. So you can setup a raid 1 (mirror) off the internal 3gb/s ports (no raid 0 though)
3. It accepts the H700 6gb/s raid controller both 512mb and 1gb. (Raid 0,1,5,10). The 1gb allows cachecade - I have one system running two 120gb SSD cache disks before writing to the raid 1...makes my 2tb raid 1, 7200 constellation drives behave like SSD's most of the time.
4. It can run vmware no issue, has virtualization setting in bios. I ran a DC, TS, and 2 workstations from one machine without any degredation.
5. Has a step mode in bios. I have mine off, but can power save on the CPU if you want.
6. Super quiet compared to a T610. I have both with 96gb ram and 2x X5670s and the T7500 sounds like a PC not a server like the T610.
7 this is a full size case - think server size but in desktop format. I personally love it, but Ive been using full size AT and ATX machines since day 1.
8. The entire case is betal and the locking mechanisms are solid. I constantly sit on them (im around 16 stone).
9. It has 40 PCI-E lanes on the chipset with access to 36 via gen two 2- 16x, 2- 8x, 1- 4x slots, so there is plenty of room for add one hardware.
10. There are several qty on ebay with a single processor and minimal ram for under $250 shipped.
for instance. This only need a X56XX processor (around $50-100), a copper heatsink (gen 2 for over 85 watt $35), a nice SSD and a good video card....try and beat that.
