hello all i have recently started a case mod of sorts involving a Aluminium Suitcase but i have run into several problems. I'll list the features of my project first which are the sources of my problems. Features: - Battery powered using an external universal battery 133 Watts but i naturally assume it can only do 90 ish watts sustained. (Yet to purchase) ( http://www.global-batteries.com.au/product_info.php/products_id/1329 ) - Build in 12v Molex Powered LCD screen Ripped from a LG566LM (Already wired up and ready to be installed) - Possible PCIE16x Graphics Card (Low powered of course). Problems: 1. Power Supply to be used. So far i have run into 3 choices. Morex 150w ( http://www.aonedistribution.com/ProdInfo.ASP?ProductID=196 ) but the problem is this uses a 4 Pin Din plug and the Battery uses a normal x mm/ x mm jack and i am not sure if you can wire up together. the m2-atx ( http://www.mini-box.com/M2-ATX-160w-Intelligent-Automotive-DC-DC-Power-Supply ) which is apparently designed for Battery powered but i do not understand the nature of the ignition "control" hence i do not know if i can actually use it with Battery and there is also the problem with the Amp Draw. The Power supply draws UP to 16 amps yet i am aware the battery has a limit. and the last one is the Pico-PSU, ( http://www.mini-box.com/s.nl/it.A/id.417/.f ). So my question is if anyone with any electronics expertise can tell me if you believe the laptop battery can be wired up to the m2-atx because the nature of a "car battery" is no different to any battery apart from size etc. and if anyone knows how the ignition feature works on that m2-atx or if i should just pick one of the other PSU's. And also if it is possible to combine two 133watt batteries to make it 266 watts since i dont know if a 160 watt PSU can make 160 watts with a 133 watt battery (althought i am told 133 is merely a measure of how long it lasts and it will merely run out faster if 160 is drawn???). But still charge both battery using one cable. Like can you hook it up parallel and charge it with one port and feed the power from 2 batteries into one PSU. 2. Mounting system. I would like to mount my gear into this Suitcase without drilling any holes right through the case or no holes at all. Does anyone have any ideas. I was thinking about attaching 4 plates to each side of a motherboard plate. these 4 plates would sit 90 degrees upwards and can slide back and forth and would be locked with screws. using this system the plates would have rubber/plastic glued on top and forced against the insides of the case keeping the motherboard mount still. But this system feels flimsy and also would take up quite a bit of space. If anyone could refine this idea or think of their own would be appricated. Also would using a perspex mobo plate prevent shorting out of pins even if it bends a little. 3. Wattage Rating. has anyone ever managed to squeeze a system into 160 ish watts. I will be using Pioneer DVR-k06, Western Digital 160g SATAII 2.5 inch HDD, 15 inch molex powered monitor, trackball or touchpad, 2 - 4 gig DDR2 RAM, Mini-ITX mobo or MicroATX mobo depending on what i hear here but i will be sticking to the 780G Chipset which is really low power and has a build in GFX if i choose not to use a PCIE16x one. i would really like to be able to squeeze a Low powered GFX card into this system to play games like Vegas 2, COD4, Grid etc. 4. Possible Keyboard idea: Needs refining. I was thinking bout CNC'ing Keyboard keys out of Aluminium or Acrylic/Perspex and engraving the letters on, but one cost involved is an unknown to me atm but most important of all is the mounting mechanism behind the key. i do not know if the machines can craft it. does anyone know how complex the mounting mechanisms behind a KB is or at least how simple can they be. Note: at any rate it would have to be a low profile style mounting which is my dilemma as they look like scissor action mountings. IF anyone can think of any problems i overlook please feel free to point them out heres a CAD of the internal space of my Case after i stripped out the interiors."
