I'm currently looking into getting some equipment next month. Most notably, the following:

• server rack (no taller than 50in. or 28U)
• 2-3 4U rack drawers, for spare parts
• 2-3 rack shelves (AP+switch, drive cage)
• a decent PDU

Keep in mind, a DL580 G7 will be sitting in the rack - just over 100 lbs by itself. Not looking for cheap crap. 

Here are some of the racks I've been looking at, for reference:

Let me know if you have suggestions. There is a potential budget of 200-250 USD for the server rack by itself. 

However, prices like this don't stick around forever - one month (maybe a week more) tops. If an affordable decision can't be made by then, the funds will be reallocated...
